I can give you my standard joke answer to this question. The most attractive feature in a partner is that they’re a person of good taste. How do I know they’ve got good taste? They’re attracted to me!
But the real answer for me is that spot on the side of a body where the hips meet the abs. You know when you’re slow dancing, the place your hands just fall to? For some reason that’s just the best.

that's a great lucky number. Mine, against all odds is 13. Been very lucky using it. Except of course in the lottery, lol.

For me, maybe the very thin and soft hair in some women's arms and lower back. That's an incredible turn on for me since I was really young.

Glasses. I don't know how that developed but I get knee weak for women with glasses... 🤓🥵

Might not be unusual though...

A low raspy voice will absolutely start my engine.

A friend i had several years ago had the exact voice and listening to her would make me chub up...no attraction in any other way.

Girls with nice nails, and hands in general. My brain immediately pictures them grabbing my dick.
