Hi! You can present feminine, masculine, androgynous, to fluctuate in between or to have your own personal identity. That doesn't say *anything* about your sexuality. They're often linked, but not always connected. I have friends that are gay and besides the obvious jokes and mocking of their own stereotypes, they are normal dudes that you would never guess the sexuality of. Don't feel like you have to be a certain way to be accepted. And that goes in any direction. Don't feel compelled to be "straight" in order to be accepted by the straights, don't be compelled to be "flamboyant" gay in order to be accepted by the gays. Be you, be happy, and try to work through life in a way that satisfies yourself. The rest? Fuck them. Also, with all due respect, a big "fuck you" to your father.
Okay Well.... Your 15 yrs old & your very young & let's be honest not long out of puberty & if you don't mind me saying that you are still maturing growing developing into a man.... Give yourself time as your feeling's & attractions to other men mite go away(or mite not) as you continue to grow. I am very aware that this is a sensitive subject in the Times we live in were it's okay to be however you want to be sexualy , i don't know if my advice is helping you or making any sense.... Please Don't underestimate getting counselling to help you who specialises in this area. All the very best to you young man your lifes walk.
