The penis is a male organ used for sex, recreation, and urination.
Contrary to feminist narrative, a penis is worth approximately $80,000, given the current rate for phalloplasties.
Early Penis Development Biology
The mushroom tip on the penis is a grown baby clitoris (and the female clitoris is basically a micropenis). Both the adult female clitoris and the male homologous counterpart can and do become erect.
Your penis shaft is basically tubal “roast beef flaps”. That line that goes up from taint to your mushroom tip are the vestiges of the fact that you used to have “roast beef flaps”, but they fused together, creating your shaft.
