What's something that turns you on, but isn't necessarily sexual itself?
I, for example, am very turned on by contrasts. So noticeable height differences, size differences (individual body parts or the whole package), skin tone, shapes, etc.
I kinda wish my wife (who's very pale) were bi because I would love to see her have sex with a dark skinned woman that's a similar height and weight as her, or a short, petite woman (she's also tall for a woman).
Yay! I remember some guy on Reddit saying he would not date anyone with straight hair, he just was not into it. Only wavy, curly, or kinky hair did he find attractive. I can see the beauty in smooth flowing hair personally, but would not want it for myself, curly is livelier.
