That isn't always the case. I know a girl who dated a girl and they both dressed like very pretty girls.
I also know two men who dated, and they were VERY manly.
It's all dependent of the PERSON'S preferences.
Maybe a woman wants to feel more like a woman in the relationship, so she chooses a woman who wants to be more manly.
Or vice versa.
Maybe he wants to be more feminine in the relationship, so he chooses someone more manly.
Or vice versa.
I hope that cleared things up for you :3
Of course! Some of my favourites (currently) are Heaven Help Us, This Is How I Disappear, Vampires Will Never Hurt You, and I'm Not Okay (I Promise), and if I don't stop now this list will go on forever and ever :P If you wanna watch a funny vid, I recomment I'm Not Okay :D
