I'm in quite a pickle... at different times I have issues with both getting/maintaining an erection, and also not lasting long enough in sex or oral. I would venture to guess part of it is pornography.

I think the problem with ED is 95% psychological in my case. I've gotten used to unrealistic expectations with women due to porn (and also getting lucky with some hotter girls in my early to mid 20s), but with the majority of women, I'm not as into it, or I find something that puts me off a bit. For the last few years it's been mostly just me and the old hand, so I've gotten used to that. Also part of it could be nerves or performance anxiety. Sometimes I start off hard but lose it after a few minutes of penetration. Alcohol is a double edged sword in that it makes me more horny and less anxious but can affect an erection as we all know, and it kind of dulls/numbs the experience a bit.

On the other hand, I've also had many cases where I don't last very long, especially if I'm sober, it's been a little while, or the girl is more attractive (but sometimes it's just random). I even bought a Fleshlight stamina training unit but haven't gotten much better at lasting longer.

Also some of the women I've gotten with in the past four years haven't been my "type" physically exactly and I've had trouble cause of that, and I don't maintain steady enough relationships to get used to someone, so it's only a few times a year I hook up. So to cope, and as insurance, I took some knockoff Viagra before each time, and I did sort of work. Viagra actually has helped with BOTH of these problems. It makes erections last longer once I get them of course, but it also makes me last much longer at sex before finishing (sometimes almost too long). It makes it a bit less enjoyable when orgasm comes because it kind of makes it feel duller and less powerful on my end.

I then tried going without Viagra once recently after a date and it was a fiasco. Barely managed to get it up and then I ended up ejaculating without even fully being hard. Had to wrap things up with some oral/hand action for her.

I get morning wood and other things and get erections randomly sometimes, so there isn't a physical issue.

I don't want to be dependent on these medications though...
