Why do men lose erections after they ejaculate?

I'm 17,and I have been dating this guy for like a year. We just started having sex, and the other day we were going to but he wanted me to give him head before so he would last longer...then he could not get it back up. He tried hard to but it just wouldn't. Was it me? Can I just not do it for him or something?

My boy friend is 15, has never had an erection and every time we want to have sex we can't. He thought it might be a medical problem but he asked the doctor and said no medical problem here. We have tried everything. The first thing we tried was dry humping and nothing happened and then I tried grinding him they say that can be very arousing but it didn't work. I let him look at porn and nothing happened. More suggestions?

Well, there's a lot going on in my life lately and well, I'm needing help with something. I'm a 20-year-old bisexual male. Here's my problem. I recently broke up with my girlfriend, with whom I had a very long relationship. We started our relationship as virgins, and well, I still am. She had issues with sex and well it was never an issue for me, it wasn't even one of the reasons why I broke up with her, she thinks it was but . . it really wasn't. A couple of weeks ago I met a guy and, well, one thing lead to another and we had the opportunity to have sexual contact. And well, here's where the problem starts. I wasn't able to get an erection. Yes, quite embarrassing trust me. I think that due to my age it is next to impossible that I have an erectile dysfunction problem so I'm thinking it is all psychological. Is it possible that I'm so used to repressing my sexual needs due to my previous relationship that it is affecting my current one? Or is it possible that his way of dealing with foreplay is just not getting me "turned on"? There's no rush to answer my question but I'd love it if you still took the time to answer it. I do understand that you probably get flooded with dozens and dozens of questions every day! Thanks!!

Okay, here's my dilemma. I am 16 and sexually active. I've been with my girlfriend for a year and a half. We've used to have sex perfectly with no problems until about a couple of months ago. Now, I can't even get an erection and I don't ever feel horny anymore at all. I ask all my friends if they have this problem but they say no, they can get erections very quickly. I'm having a lot of trouble with this because I thought at this age teens are able to get it up quick and easy. I don't know if it's a testosterone problem or not but it's starting to wear on me. I'm in good shape, but I smoke a little bit. Basically, I've completely lost my sexual appetite. This isn't right. Someone help!

My girlfriend and I have been dating for over a year. I have never loved or felt this way about a girl. We have been sexually active ever since we started hooking-up and dated. She has the ring, and I like not having to use a condom. She is the first girl I have never worn a condom with though. At first I could last 15 to 20 min of intense intercourse and now I last 5 min tops. Why am I doing this? It also seems to turn her off and worries her sometimes cause it's not as long. I always get mad at myself and want to go again like I have something to prove. Am I doing this to myself? We do other activities and she and I both love it, I get her to come and orgasm (sometimes) but when we do this it turns me on so much. Could this be another reason why I go so fast?

This question is about Premature Ejaculation, nowhere on the internet will give me any free advice or help so I really appreciate some real advice on thus one. I'm 20 years old and I have a girlfriend.

We been having sex a lot, when I get to see her, (she lives in another city in the time being but when I do see her), the tension is high in our sexual urges and have a lot of it. I have a very confused penis as it would last normally (let's say 10 minutes) but then more often it goes out of control and I ejaculate to soon.

She is very supportive and tries to go slow or is patient when I have to stop every 5 seconds. But come on, this isn't sex. I'm fighting a battle every time. I try to relax and use different condoms for sensitivity but I still get the same end result PE! I do know I have a high sex drive ( I love the idea of sex a lot) she is hot and the fact she wants it all the time is hot too but I find sometimes it makes me a bit nervous because of my problem.

I know in my past I do get stressed, sometimes I don't sleep regularly, or get the proper exercise as needed, and I got a lot on my mind but I know others like that and they don't have PE or at least tell me that. When I was with her I wasn't stressed or anything and I still get it. Can you please help me.

When does pre-cum come out of a guy's penis? Does it come out when he gets an erection or does it come out when he is actually having sex? Does it depend on the guy?

What is erection?

Hello my question to you is this, I am 26 years old and have an ED problem. I have always had this problem. I can get an erection but I can't keep it long enough to have intercourse with my partner. Do you know what someone my age has this problem for? As far as I know I am otherwise a very healty individual, and I was wondering should I seek medical help for this problem and if so can I just go talk to a regular doctor or do I need to talk to a urologist? any help would be appreciated.

My girlfriend and I have been together for about 2 months now, and we have been having sex for about a month. I am unable to get her to climax. She has only had sex with one other person besides me, she only had sex with him one time, and she didn't like it when they did it. She had sex with me for the first time because her friends were pressuring her. I told her that I was not with her for the sex I was with her for her, but she told me she wanted to. So we had sex and she said it hurt her. It doesn't hurt her anymore and she tells me that she enjoys it, but I cannot get her to have an orgasm. I have gave her oral one time and she liked it, her legs started to twitch and afterward she had a cramp in one of her legs, but it didn't get her to reach her climax. Now she won't let me do that anymore because she thinks that it is nasty down there but I like doing it and when I did it I didn't find it the least bit nasty. She is a little bit chunky and she thinks that the sweat will make it taste nasty or what ever, but when we do have sex she does get pretty wet down there so I don't see a reason to use extra lube.

The last girlfriend I had reached her climax every time and usually two or three times. But when she left me I was single for about 10 months because I was trying to get over her. Now when I have sex I can't last very long. We have sex for about 10 minutes and I have reached my orgasm. The other night we had sex and I came and then we waited for about 10 minutes and had sex again only this time I lasted for about half hour. I am very self-conscience about my penis because I feel that it is small and unable to get the job done but I have never had a problem getting any other girls to climax. Could this problem be because she is new to sexual experiences or becuase my package is to small? Is there a way for me to make myself last longer? I have tryed masturbating before she gets here to try to make myself last longer but it does not work. I have never had problems like this before, my last girlfriend and I used to have sex for an hour or two everytime. I think she is also worried about having sex to much because she doesnt want to become "loose". So I don't know if it is her or me that is the problem.

I am concerned because I have liked this girl for a while now and now that we are together I am falling fast for her. I just want her to have the most pleasure she can out of the sex. Also she does not masturbate so she has never given herself an orgasm either so she don't know what she likes and I think she is sometimes trying to hard to get herself to experience an orgasm because I am trying so hard to get her to that her body don't let her. Also I would like to talk to her about new experiences and new ways to try to get her to climax but at the same time I dont know how exactly to talk to her about it. Thank you for your time and advice.

Hi, I'm 15 years old and I have 2 questions. In school, at home, and a lot of the time I have an erection, is that normal? And also, when I masturbate, I ejaculate really soon. How long will it take for me to last long?

I'm a 17 year old male, and when I'm with my girlfriend, I can't always get an erection, and it doesn't always stay up. Also, I am an uncircumcised male, and when my girlfriend rolls back the skin and touches the head of my penis or when she gives me a blowjob, it feels really sensitive, almost to the point where it hurts to touch it. Is this normal?

First of all, let me say I'm impressed by your mission here. A lot of people's first sex would be improved with real sex ed. My particular problem concerns erectile dysfunction. I'm only 19, yet I've experienced this problem 4 times. I've read that this can occasionally happen even to younger guys, but the last two were consecutive and I'm worried about how patient my girlfriend is. Is there anything I can do for this particular problem, maybe drugs?
