39.
When my SO takes off his belt. Even if no sexy times are involved just nnnngggghhh.
But other than that, hair. Chest hair, beards, and abbey trails. I give the boo tummy rubs all the time because I can play with his abbey trail and go up and run my fingers through his chest hair and then go play with his beard. He thinks I love giving tummy rubs because it feels good when really I’m a selfish bastard and only love him for his body hair.
