Am i gay? (I'm a boy)?

lets get thing straight (pardon the pun) i love females, im ually attracted to them, i check girls out etc etc, i like girls, but sometimes when i see a guy i feel wierd and i mean i think the are good looking, does thinking a guy is good looking make me gay? im confused, even thinkin about going out with a guy grosses me out, but i still sometimes get that strange feeling, if youre gunna say something stupid then just please dont say it. Some other info is that i like music and art, i dont sdo sports, and i have lots of friends that are girls
