You are: Lesbian by default. Since the only way you could cause an erection involves legal blindness and a Warn.tm winch.. Go with it. You are a perfect example of why real world lesbianism is never as pretty as girl on girl porn.

Keep chewing your cud and flapping your lips though, as you are also in season.
