my roommate and I are addicted to smelling each other's junk

Basically yeah, I mean if he's really nosing me I might get a semi but who doesn't when they get a little fondled?
Or if I kneel over his face while he's laying on his back and push his head into me he may get hard, but only because he enjoys the domination side of it. I don't consider it gay to enjoy something thats non-woman. And I don't consider it gay for two very close guys to share something they both enjoy and help each other out sometimes.
