I’m not a man. At least, I wasn’t the last time I checked. I swing both ways, though, mostly theoretically-speaking. I made out with my best friend once when I was around 19. We would’ve been together if it wasn’t for religion.
ANYWAY, if I HAD to pick something that wasn’t personality, I’d say facial features. Maybe nice eyes and/or a nice smile. Most people have something attractive about them in my opinion.
My friend had nice eyes. We grew up together, were best friends, and I was in love with her, so it didn’t really matter what she looked like. I would’ve thought she was gorgeous no matter what.
