I don't know what my problem is ?

Im a 16 year old straight male . I was raised in the ghetto & still live here . I used to walk straight but now i walk like im gay, but im not . People on the block call me a fag, though for fun, & most of my close friends are starting to get suspicious of me . If this keeps up, im gonna lose it . Ive constantly told them i wasnt . I walk like a fag, I push my right leg forward & it looks like im walking like my pants is falling down . Sometimes i lowride cause my legs are pretty lanky too . Ive been weight lifting alot too , but that isnt the problem . The problem is i dont walk straight, my back keeps curving inward, my but keeps sticking out, & my legs look bent, i walk like im limping on my right leg too . IM NOT GAY, IVE HAD SEX WITH MY GIRLFRIEND MANY TIMES . IM NOT A BATTIMON EITHER, & i dont want people thinking i am, what do i do ? HELP MEEE .
