I'll say it once, and I'll say it again.
So many teenagers claim to be biloveual for attention / to seem different, without going as far to claim they are homoloveual. Bullstuff that any of those people actually have any attraction to the same love.
In 2009 half of my school suddenly became biloveual for a month. Stupid fad is stupid.
I'm 19 and I've known I was biloveual since I was a kid, I came out when I was 16. I've always had an attraction for men that I suppressed because I grew up in a christian household where I was taught that gays were an abomination against god. I felt horrible, thinking I was going to hell for being myself. But I finally realized there was no point in feeling bad for such a natural thing.
In other words; don't be so quick to denounce people. The fakers will be fake but some people really do know themselves.
