My girlfriend doesn't understand why we can't have sex because I'm not ready. I keep asking her to wait a little longer, but then she gets confused and she thinks I'm not interested. I just don't want to mess up or get an STD. I don't know what to do.

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?

I'm 17 and I have a boyfriend of 7 months, and we're both very much in love. We had sex 4 months ago and he didn't reach orgasm and I got the sense he was frustrated so we stopped trying until last weekend. We both really wanted it but the same situation happened where he didn't reach orgasm and I feel like it's my fault and that I'm just not hot enough for him. I never reach orgasm during sex but I always enjoy it and I want to have sex but the problem is I don't want to do it if he's not enjoying himself or feels frustrated and I also don't want to come off as though I want sex all the time because I'm his first girlfriend and he hadn't done anything sexual before me - not even kiss - whereas I was not a virgin upon entering the relationship, so I don't want to come off as if I'm a rushing things all the time. After all this, my question is: What can I do to make my boyfriend enjoy sex enough to orgasm? He has never finished during sex and I get the feeling he's frustrated with it and would rather I suck him off but I always want sex when we're fooling around and I love him so much I want us both to be able to pleasure each other at the same time.

My Boyfriend and I are new to doing anything sexual. We are both virgins and have never had intercourse, just oral. How do I tell him what he is doing does nothing for me and doesn't please me without hurting his feelings, and what should I say to him?
