Hi
Me and my boyfriend have been together for quiet some time. I completely enjoy sex and so does he, but I have never had an orgasm with him. Come to think of it, I dont think I have ever had an orgasm with any guy... I have them everytime when it is just me, but it seems like I have trouble with a guy. I came really close one time, but the guy had a bigger penis than my boyfriend (he isn't as big as most guys). I have tried being on top but with him it doesnt seem to matter how I try or he trys. Any suggestions on what could help?

Ok sometimes people have psychological problems with orgasming during sex, but most of the time its simply a physical problem, and all that's needed is the right technique, or maybe the right setting.

The first question is, can you have an orgasm on your own while masturbating, while stroking your clitoris, or maybe with a vibrator on your clit? If you can, then all you have to do is to use the same ideas when you are having sex.
First you can stroke your clit (or use a vibrator on it) while you're having sex with your boyfriend. Then you can show him how you do it, or maybe get him to read the clit section. Especially when you're on top it should be easy to stroke your clit.
