Erectile Dysfunction question
I have had the problem of maintaining an erection since the day I lost my virginity (that was at age 20. I am 30 now). I have a hard time getting an erection, maintaining an erection, and even maintaining an erection during intercourse. I went to my doctor about it recently and he suggested me trying Viagra. So, he gave me some samples. I tried it, and well, it worked! I actually felt normal. So, here's the deal. I don't want to take Viagra for the rest of my life, and I don't want to pay $10/pill. My current girlfriend is getting frustrated with this problem of mine, and I HAVE been frustrated. She says she'd never leave me because of it, but I still want to do something about it. I was thinking that since Viagra works, it's maybe not a physical issue. I get the occasional overnight erection while sleeping. I'll even get one out of nowhere sometimes in general. One thing that has never really happened is me getting an erection from looking at a porn magazine, or anything like that. But if I think about a sexual act (such as a woman masterbating, or something to that effect), sometimes I get an erection (Sometimes this erection will last for 5 minutes, sometimes it goes immediately away in a matter of seconds after I realize I'm getting an erection). But when it comes to me having sex with my partner, once I get to the point of penetration, or even close to it, I either lose my erection, or I lose it during intercourse. Even mostly while we are being "intimate", kissing, etc, I get an erection, then out of nowhere, it just goes away, and at that point, I can't get it back unless there's stimulation involved (like her rubbing on my chest, or if she does oral... sorry if too graphic) I am going to go back to my doctor about it again, but I wanted some input from other people. I was thinking about sex therapy, or I even read about hypnotism (I don't believe in hypnotism, but thought I'd mention it here). Does anyone have any input/suggestions/advice.. Anything is much appreciated!
