"this is really common with African American men, under the age of 50, in the South"
R33, it's also become really common among white men on both sides of 50, at the fringes of the South, where I live, which used to be a totally homophobic area.
I meet men of all ages who are in apparently happy relationships with women, but who also like to fuck and suck other men.
The really young ones, early 30s and younger, say when they were in high school and college, lots of straight guys would try gay sex, and even if it turned out not to be their thing, they were cool with it and just went back to their gfs, but a lot of them liked it enough to keep doing it now and then.
The older ones seem to have decided to try sex with a man after gay marriage became legal and so many people who were formerly closeted or just didn't talk about it much became more visibly gay. Most of the ones I meet are married and have children, and they just like getting off with a man. No games, no strings, no need to jump through hoops to get their woman in the mood. They just run out to do some errands and make a quick stop to swap head with a guy.
Then I also meet plenty of retirement-age guys who say they always wanted to have sex with a man but were afraid of being found out. A surprising number want to do some kind of role-playing game that reminds them of playing around with a friend when they were an adolescent. Probably because they've spent the last 50 or so years fantasizing about their 7th-grade experimentation.
I wish I could meet more African American men, but I'm white and old, and apparently not as appealing to them. Not that I'm attractive to white guys, either, but for some reason, white guys on the DL from young to old seem not to care much about my age. They just want sex and are willing to get it wherever they can. Also, most don't just want to get a blow job and leave, they want my dick in their mouth, too.
I'm not saying these guys are straight, just that they live apparently straight lives. Gay men are very different and are not attracted to me or any old dude in the least, as we all know. But these apparently bisexual men just want dick, regardless of age or hotness factor.
