My boyfriend and I have sex often, and when we do we use a condom as often as possible. But when we go to get condoms there are so many to choose from! There are ribbed ones, spermicidal, ones that are specified for "her" pleasure and vice versa, ultra thin..and more. What is the difference in all of these? Do any of them really give more pleasure or feel any better than a plain lubricated condom?

I'm 17 and wondering if there was anyway to make myself wetter down there, or if I could make myself tighter? My boyfriend tends to like sex more when im wet and tight. I do feel like im wetter if I drink more water each day (like 2 water bottles while I'm at school) Is it because I'm drinking more fluids, or is it all in my mind?

I get tight and loose randomly but I feel really small when we have sex less often for long periods of time. Like have sex on Monday, and then don't do it again till Saturday. I know the vagina naturally changes shape and becomes looser or tighter. But I want to know if theres anyway to make it tighter. I love having sex with my boyfriend, but I want him to have fun too (I know he does) but I want to make it more enjoyable for both of us. He tends to explode when I'm wet and tight, and we both enjoy that. Thankies to you if you can help.

I'm 18, and my girl and I have been going out for a year and we have just recently become sexually active so I have a few questions.
1. Is it okay to use spermicidal lubrication,or a spermicidal condom, because I did research and it may harm my girlfriend. I definately don't want to do that because I truly love her.
2. We've tried anal, and once I ejaculated inside her anus, is that ok? Every time I try anal it hurts her, how do I make it feel good for her? I don't use lube, and I am very careful, and hate seeing her in pain.
3. Is it ok to use water, spit, or saliva for lube to go in her butt?
4. when I eat my girls vagina she really likes it, but I want to get maximum stimulation, how would I do that?
5. Is it ok to have anal sex or will that mess her intestines up at all in any way? I just want to make sure it's safe, okay, and won't harm the love of my life.

What happens to natural female lubricant (or any other moistness) after intercourse? I have asked many of my friends (both male and female) this question and no one can provide a sufficient answer.
All the information I have so far been able to glean on the subject is that the vagina is a "self-cleaning organ." I'm not stupid. I can imagine what this means, but I would just like it explained a little bit more in depth than that. Any information you could supply on this subject would be deeply appreciated.
