I can see what you mean about getting biased responses. I'm interested if many gay men experience ED if they're with a woman.
I've searched everything in the house, yard, and cars and I've found nothing pointing to gay. But like you said why would someone say something like that? And why would he be able to use condoms with someone else. I've been feeling self-consious about my looks around him, but I've never had a problem getting the interest of good-looking men, and I've gotten a lot of compliments on my looks, so I don't see where there's something different about me and the average woman unless he can only date supermodels and it work right.
