As a person who is completely 100% straight I can't help but notice bisexual women seem to be much more accepted than bisexual men by greater society but especially by women.

Straight men seem to not have too much of an issue with having sex, dating and even in many cases marrying bisexual women. (Unless they're extremely religious)

In the other hand straight women seem to have great aversion in having sex, and especially dating and marrying bisexual men. Heck I've even read stories about bisexual women openly rejecting bisexual men which always seemed odd to me.

So my question is what do you think causes the difference in this dichotomy?
