This could be a long list. His body type, his hair, muscles. Mostly muscles. Some women find tattoos sexy (I am one of them). Also hair can be important too. I like my partner's chest hair, and his puffy blonde yet brown head hair. The tattoo he designed and had put on his shoulder. His back, the way his muscles overlap, then the way he has no hair on his back so it's easy to view. A strong chest and stomach to adore and curl up on.
