Lots of things. Moaning makes me the horniest but being touched touching myself. Looking at my big tight ass or my sexy big tits above all my big long fat cock. I always fantasize about my lover seeing pictures of him naked. Someone who smells like B.O. groom yourself Take a bath, make an effort splash Some Cologne on your Self. We notice these things and we do appreciate them. In most cases, if you're a stinky guy, you probably aren't gonna get very far, so keep that in mind.
