Hah, I'm lying if I were to say it wouldn't be hot if a girl were to magically able to grow a penis and let me jerk her off then it disappears when she cums. I'm not gay but I feel that an erect penis is the best sign someone is aroused, how hot would it be to meet her or a girl you have a crush on and she blushes and pops a huge boner and has to cover it up with her purse and you can tell the pressure of holding it down with her purse is making her even more aroused.
