I removed the point about today since I haven't been dating in a few years, but I stand by the 2010 comment, you could find a few female stars being openly bisexual for example but it was incredibly rare for male stars, which is indicative of how hot it was perceived at the time.
I gravitate towards bi/pan people anyways due to my androgynous features.
For what it's worth I found a blog post referring to that phenomenon from a few years ago which talks about a poll conducted in Glamour Magazine: https://web.archive.org/web/20160320094402/https://www.pride...
It's simple, you make a profile, talk to people, people talk to you... Why is that so hard?
"63% of women, however, say they wouldn't date a man who has had sex with another man" https://www.glamour.com/story/glamour-sexuality-survey
If you do some casual searches you can find qualitative and quantitative data supporting the idea that unfortunately for bisexual men, male-attracted women are not into them and you're incentivized to hide or downplay it if you want to appeal to the broadest group (though I'd argue you may as well focus on those that can accept male bisexuality if you're successful enough at dating).
This is simply not true.
Maybe I'm just hot enough to overcome the queer disgust? I don't feel like I'm that hot.
