Help me get my mojo back

[confidenceneeded]

I have a great dh of 10 years and our relationship is good. The only problem is the lack of adventure in bed. We have regular sex (3-4 times a week), but always him on top.
The problem started when we met. I was much more confident sexually then, but he suffered a bit with losing his erection, because he was nervous, and he couldn't ejeculate inside me. I think this made me feel a bit inadequate etc., even though i know it was actually nerves on his part.
Roll on to now. He never loses his erection, can come inside me and he is confident in bed now. But i now find it hard to relax and struggle to come when on top of him (i always come when he is on top of me).
I need to regain my confidence, because i feel i am boring in bed (even though dh doesn't say or imply that).
How can i feel super sexy and confident?

Take about twenty steps back. :) Sex is so much more than who is on top of whom and who orgasms how. In fact, focusing solely on the finale can be stressful and take the fun out of it. The enjoyment in a murder mystery is not the last page when you find out whodunnit but the twists and turns of the plot that get you there IYKWIM. I'd suggest you work on being intimate, confident and relaxed together in every other physical way you can think of barring actual penetration. Bathing together, cuddling on the sofa, massages, kissing in public, holding hands... Once you both find ways to enjoy intimacy more, good sex will follow.

cognito Do you write for a living because you have a great way with words?

You have hit the nail on the head i think. There is definatly a lack of intimacy in our relationship. This is not intentional at all. I truly love and fancy my dh but i think we have become lazy in that area. He worked away before christmas and when he came back we were really intimate and i was much less inhibited in bed.
We need to find a way of not letting things get in the way of that.
