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).
that’s where all of my sexual attraction comes from! I don’t really get people thirsting over a random pretty person being naked. But make that person dominant and caring and I’m down.
I particularly enjoy those traits in potential sexual partners:
Dominance, creativity, intelligence (if you’re smarter than me I’m already on my knees), size difference is also good, confidence, assertiveness, caring, simply being a nice person to be around & being able to be emotionally vulnerable.
