My girlfriend and I have a really good sex life, but she can only orgasm in one position. She enjoys other positions when we're together, but she still can't reach orgasm, even after a while. Advice? I really like to please her and it makes me feel inadequate sometimes.

1. You should be stoked she CAN orgasm.
(many women on this forum cannot)

2. WHAT is the position she likes?

There are other positions to suggest once you inform on that.

3. I would simply experiment with little stress about it

4. try a new position.. and manually stimulate her clitoris, or let her use a vibrator in that position.

I am VERY stoked that she can orgasm, although it took me a while to figure out exactly how to get her there. We've tried many different positions, all of which can bring her on the verge, but can't quiet get her there. The only one that is a sure thing is missionary, although that usually takes a pretty long time and a lot of effort to get her to climax that way.

She's young.
You're young.

Relax... many more things will happen in time.
