I am sharing a house with three other guys but having real problems being hared by one of their work mates?

I work as a male nurse and am ually straight but their truck driving mate, keeps touching my backside and trying to tongue kiss my ear. Do I break his jaw and several ribs and lose my career pending serious ault charge.? This trucky insists I am the one who is gay but I know differently. I enjoy my job nursing and helping people get better, but this buffoon keeps on bringing my occupation into question. I do work with some gay people and they teat me with respect but also know Im not attracted to them ually. Could it be this loud fouled mouthed, booze besotted, truck driver is more likely the one with the tendencies?. Moreover, I really feel my privacy is invaded, as this ape comes over to visit the rest of the house members on a regular basis to drink and play cards. I sit quietly studying in my room but am always confronted with him in the hallway. Should I kick his into orbit next time he gropes me?
