how would u know that u are gay????

Why do you feel confused? I heard there are different types of homosexuality so it can be confusing.

I do not think one actually comes to a conclusion if you they may or not be. I think people can be in denial, confused or not able to accept. So in respect to your discussion I think it's pretty clear to someone who may wonder whether yes or no if they are gay. It is not that they do not know if they are I think that they are actually curious as to what it would like.
