For me it was the awareness that the Condom Edict of the early eighties, that we thought was only going to last five years, was still in force thirty years later. Anti-retrovirals mean that I'm essentially non-infectious (I can't rule out the possibility of blips in my viral load, but a jump to infectious levels would most likely be accompanied by illness of some description: the normal blip is less than 100 points) and superinfection remains pretty much theoretical in that it happens about once a year in the entire world. So why the hell not? I couldn't think of a reason: I'd been BBing with other poz guys who I knew reasonably well since the late eighties, and loathe the sensation of rubbers (to me their only use is to deny a bottom the cum he wants as a punishment). ED makes it rare for me to fuck as the standard remedies don't work or give me all the side effects and none of the fun, so I'm more likely to end up getting my ass filled. Shit, but I've missed that sensation!
