We had a virgin with no experience with men study penises! We had a virgin who had never even seen a penis draw a picture of an erect penis from her imagination, then we showed her a real penis, pretending it was a normal size, and showed her a huge penis! 3 out of 7 virgins were surprised by the size, which was bigger than they had imagined, and it was a great success for them to have sex for the first time!
