Personally - if I had a Male....I probably wouldn't put a shirt like that on him UNLESS it was in a room full of jocks watching a football game.....
What about something less graphic ? I made Chanel a shirt that said "Bite ME !" on the back - then made a shirt for ME that said - "Bite Me Too" ...it's cute without being offensive. The sayings you choose I wouldn't want little kids reading....Sorry !!
