Yeah, I mean, you're correct. But the way I knew is by asking myself if I would protect, love, care for, and stand up for my girl just as a guy would. P.S, I'm a girl. And hey, you can come out to anyone you trust at anytime and/or age. I have had a lot of people tell me, "Oh... Yeah its just a phase. You'll get over it." But DO NOT LISTEN TO THEM! YOU ARE THE ONLY PERSON IN THE WORLD THAT KNOWS YOU BETTER THAN ANYONE.
