The only qualification that I have personally is that I am a guy, but I would like to give a little support to you. The gender gap is a tough one, relationships and intimacy issues are hard to get a handle on at times. I have "practiced" most of my life, and I guess that is normal. I am in a fairly new relationship, and my girlfriend wants me to "practice" with her, which was really difficult for me as I have never been that open about it. I was never in a relationship where I masterbated in front of my girlfriend. I can say it was strange at first, a little uncomfortable. I really enjoy it now, and it turns her on as well. We often have sex when I intended only practice. I don't know if this is something you might be able to try, it just worked for me.

Good luck, and good for you for writing about something that is so tough.
