I know jockstraps for athletics have basically been replaced by new types of spandex support. That being said, are they now really just lingerie for gay men? I think they are extremely sexy on a guy. It’s a huge turn on and I imagine I’m not that different feeling that way.
I'd say it's a matter of opinion really but I believe they're marketed at all men, regardless of sexuality, however I would guess that the bulk of the purchases may indeed come from gay/bisexual men and for this reason, it is why I own a few. I can wear them to express my sexuality without anyone actually knowing. Do I feel gay wearing them? Yes
I get that, and I'm a bisexual woman not gay man. Anything strappy is cool...thigh highs and garter straps, think of rocky horror picture show...
A guy in a jockstrap or thong is really quite sexy and erotic. I now see where they are marketing lingerie sets for men and those look really nice and sexy. I would suppose they are basically marketed to the gay or fetish market but they look great.
