Sometimes I wonder about this. I'm a young teen, my whole life ahead, lol, but still. I can swing one way or another when it comes to gender attraction, ya know? If I like the person, then I like the person.
That being said, I'm mainly into fem dudes. The few girls that I've been attracted to have been androgynous lesbians, so that avenue is pretty impossible.
I believe in the inevitable. There's someone out there for you, someone that will click with you, love you for you, etc. Dude, you'll find someone special. Don't get too depressed. The super amazing sexy lovable perfect partner won't judge you on genitalia.
