Is there anything about other people’s bodies that you find irresistibly attractive ?

Long fingers

I think it's cute when women have beauty marks on their titties

Edit: or ass!!

A nicely-trimmed bush that still covers the labia is ideal, my wife was surprised I didn't want her to wax

So right after doing physical labour or just a work out some guys just smell so incredibly arrousing, the smell of new sweat and then the muscles all pumped up. Gets me going.

For me, it's an open, honest, ready smile that lights up her whole face. Smiling from the eyes, as it were.
