Is long hair generally a no-signal to homosexuals?

I get a LOT of unwanted attention from homosexuals when i actually just want to be buddies for sports and hobbies and stuff. So when my friends realized that im in no way, shape, or form gay, they slowly withdrew from the friendship. So i was alone for quite some time and now i have a new group of friends that i suspect to also be homosexual. So when i find out that they also are homosexuals i will stop to make friends. Like, WTF, can't they just tell me from the beginning that they just want to violate me sexually, like, before pretending to be friends when they actually just want sex?? It's just ******* ridiculous. I even grew long hair in order to be a turn-off for them and cause i just like it. Maybe they think i'm gay cause i never had a girlfriend but i just have problems finding one and i just generally had bad luck with that. Is there any sign that i can give to be a complete turnoff?
