Just Found Out She Has a Penis

It sounds to me as though you went to bed with a hermaphrodite, which is a person (or animal) who was born with both male and female reproductive organs. The outward physical appearance of human hermaphrodites may skew more toward male or female, but the genitalia and reproductive system will still exist ambiguously. Different hermaphrodite humans may have different systemic characteristics: Some hermaphrodites will have a both a penis and vagina, while others will have a phallus that is somewhere between a penis and a clitoris, and partially closed labia. Human hermaphrodites may or may not have breasts at the same time as having a partial- or full-size penis. Many hermaphrodites will experience menstrual cycles and bleeding, although infertility is a noted and widespread problem among hermaphrodites. This is not always the case though, as in the 1600s, a hermaphrodite living as a woman in Scotland was put to death (buried alive) for impregnating "her" master's daughter.  Human hermaphrodites cannot self-reproduce as they are not born with two complete sets of reproductive systems, causing some key elements in biological reproduction to be missing from the equation.

The question isn't whether you SHOULD or SHOULDN"T bail versus experiment, but rather what do you want to do? There are no rules. Just follow your heart and let it lead you where you want to go.
