@ThaneIt's alright, it makes sense that you'd put hetero as they're attempting to find out more about themselves. And in all honesty, Nathan is my first homosexual character, and Blake is my first Bisexual as I'd thought I'd change up how I roleplayed, seeing as I usually roleplay as girls.
It's also the main reason that I made Nathaniel closeted as he himself doesn't really want to accept the fact that he is, while Blake, being the more outgoing and confident one, doesn't care what other people think and would easily announce he is. To me, it's just another way to see a different viewpoint and make for a more interesting RP.
I will say that you shouldn't force yourself to RP as something if you don't feel comfortable with it. Just do what you want to, and have fun with it ^_^
