(raises flame-shield) I don't really believe in bisexuality.
Now, don't get me wrong, you can be whatever you want to be, no judgement from me.
And to be honest I haven't ever considered this question until this very moment.
But in my own personal experience, those claiming to be bisexual tend to be in the 16-26 age bracket, and after that, well they pick a side.
So, if a man was to experiment with other men, yet ultimately settle down with a woman and have children, I would see him as a straight man who did some experimentation, not a bisexual man who just happens to be with a woman.
Again, this is my own experience. I have friends that wear the title of bisexual like some kind of pretentious hat.
Almost like its some kind of fashion statement.
P.S. I also notice a lot of people claiming to be asexual on the Escapist. While there is indeed such a condition, it is medical and not societal. My advice to these virgins is to take a shower and talk to the girl/boy you like.
Opinions, I have them
