It took me a few viewings before it clicked (and I understand not everyone can afford to do that), but I did actually ask Chris Herbie Holland and the whole monologue is meant to be Tio's "coming out" story in a way. In the beginning of the play, he is aggressively heterosexual in presentation (playing porn out loud and simulating sexual positions with a balloon).
However, once he comes back and he's high as a kite, he realizes through his stoned sexual interaction with the gingerbread "man" that his sexuality is far more expansive than he previously realized - and that helps him relate and gel more with all of the other young characters who are in different stages of reckoning with their sexuality - Pride (Opal), Indifference (Juicy), and Repression (Larry)
