It's terrible, but it's true.
"Dude, you're seriously straight ???" That's a question that might get someone smacked-up in the wrong circumstances (sadly these "wrong circumstances" probably occur more often than imagined).
"You sure you're _____ ???" This comes naturally all the time, from straight friends and even family of a gay, lesbian, trans or bisexual. I've heard it myself from the most personal of sources.
I've only been "out" for a few years now and I have to admit I've even found myself questioning my own "gayness" now and then. It's not that my preferences are in question, but what about my tolerance ? Perhaps I could deal with a woman partner of some sort. Just to fit in.
I've convinced myself that I was born perfectly bisexual, and this might actually be true. When I was young I often enjoyed sexy lady pics and videos. But then again a nice breeze in the right direction, and, well.... you get the picture.
When alone with a porno mag, the ladies were hot to be sure, but I really preferred the magazines with couples getting it on.
But it was the small ads at the back of a Hustler or another "specialty" magazine that really drew my attention. There were sexy dudes naked, and gasp even getting it on with other dudes behind black censor circles.
And when I really dig into my memories, certain guys in high school captivated my imagination.
So ya, mom, I'm sure.
I've probably always been gay.
And I've never been more proud of it. I'm special.
Happy, on the other hand... that, I'm still working on.
