I'm almost 29 years old, and have struggled with self-confidence and anxiety issues for most of my adult life. Prior to meeting my current girlfriend, I'd only ever had sex with one other woman, when I was about 23. So, it's been many years for me. When I met my current girlfriend and we were first starting to get to know each other, I was able to get and maintain an erection very easily, but when we started actually having sex recently, I've found that my extreme performance anxiety is preventing me from maintaining an erection for more than about one minute of sexual intercourse. Even though the desire is there, I psych myself out and start worrying so much about my performance that I lose my erection. Fortunately, my girlfriend is VERY understanding and willing to take things at my own pace, but I can't help being very frustrated and worried about the fact that she's not being sexually satisfied.
A couple nights ago we masturbated each other, and I was able to maintain an erection and eventually reach orgasm that way; however, even oral sex can be somewhat difficult to stay erect for. I tend to think that years of masturbation (I tended to masturbate about 4-5 times a week) has made it so manual stimulation is the only way I know how to reach orgasm.
It ALSO doesn't help that I'm currently on Celexa (Citalopram) to help control my anxiety; I've been taking it for about 6 months now. I definitely noticed much greater difficulty in reaching orgasm after being on the Celexa for a couple of weeks. Sometimes, even while masturbating, I find myself losing my erection before reaching orgasm.
I've pledged to stop masturbating for a while except with my girlfriend, in an effort to try to get used to being brought to orgasm in other ways. I don't have a check-up with my doctor for another five weeks. I definitely plan on talking to him about this, but until then, does anyone have any advice on how I might be able to maintain my erection long enough to achieve orgasm? Thank you in advance!!
