I'm 18 and have been sexually active with my boyfriend for about a year. We've done all sorts of things with each other, including oral sex. However, he refuses to perform oral on me. I've given him blowjobs many times. He says he enjoyed it very much, except he felt bad because he didn't want to reciprocate. He says that if I don't want to give him a blowjob, he would completely understand. But I love giving oral; I don't feel that it's unfair to me if I choose to do it. Even so, I really wish he would go down on me. When I asked him why he doesn't want to, he said he doesn't know. What could be bothering him, and what can I do to convince him that giving me head isn't as scary as it apparently seems to him?

I've had one my questions answered before and I'd like to thank you for answering it because it was very useful :) Now I've got more!

• Sex with my significant other has been wonderful the past few times we've done it, emotionally. I still wonder about physical, though. I have orgasmed before but only with my own clitoral stimulation. Is there a possible way or technique used to attain vaginal orgasm?

• I've also wondered about unprotected sex...I have not done it yet, but I don't want to rush into things before something bad happens. I am on the pill and we were both virgins when we started. So I know that there is no possible risk of STD's. I heard it feels better for both partners with no condom, so what are my risks and options?

•I always thought that sex in the water was unhealthy. Then I came across a book in my local sex shop about how to have sex in the water! Doesn't the water ruin the latex of the condom or is it safe not to use one in the water?

I am very confused about "popping my cherry". I have previously read that everyone has to have their cherry popped, but then again some say that there is no skin thing. If not, than why does it hurt when you have sex for the first time or why do you bleed?

My girlfriend and I have been having sex for over 2 years now, but she is still very "tight", and really has to get into the mood before I can penetrate. It's almost as though we're having sex for the first time, every time. Sounds romantic, but it's a bit annoying for both of us (and she finds it painful if I accidentally push too quickly). With my ex I could slip a finger inside her without any hesitation, of course I would never mention that to my girlfriend. Once we're into it, there's no problem with going harder and faster, it's just that initial thrust. Is this normal? By being so gentle the first time have we possibly never broken her hymen? Otherwise, if we have sex more frequently, rather than maybe once a week/fortnight/month (for now we both still live at home with our parents) will she likely open up a bit more?
