For me, this has always been a problem. After all, there are no bisexual bars and there's no bidar equivalent of gaydar. I'm not much into bars anyway and Adult Book Stores seem like an easy place to catch a disease. Although I have a personal ad at this site, I've never gotten as much as a nibble. I started with Adult Friend Finder and had some success. Then tried CraigsList, which still use occasionally. For a while, I was even in a bisexual group at the local LGBT center although that turned into a therapy group and I couldn't handle all the psychodrama. I've met a number of men over the years, some for a one time and others for a period of time. But it seems like when you get older, all you find online are married men on the down low. No conversation and they are seldom interested in anything other than a quick suck.
So I would be interested in hearing how you go about meeting other bisexuals, for sex or whatever. And what have been your experiences?
