Need help.

There's this really cool guy at our school, and we have a great friendship. And i mean, i am straight. But because of this guy i feel like i should not. We always bump into each other and touch each other often. Sometimes he lies on my shoulder and touches my legs (o_o), and he always talk to me in a 'girly' voice, would you think he's gay and possibly likes me? PS. He sometimes hits my penis (when i have clothes on dont worry and im okay with it cause i hit him back >:) ), and both of us are males, 16. Once again, would you think he's gay and possibly likes me?Edit: We hang out alot.
