he also made the mask and some of the sets for 'v for vendetta' amongst other things, so it wasn't a diy casting kit, it was done professionally. I don't know how good the diy ones turn out tbh.

This is actually educational. How many straight women get to get up close and personal with a number of other woman's genitals in order to make a comparison? When I was a moderator for Scarleteen, I saw a number of adolescent women worried about the size and shape of their genitals. Fortunately another moderator was a nurse specializing in obstetrics and gynecology. That means she has seen female genitals from infants to geriatric care. She gave out a lot of advice as to what is "normal" which is to say almost anything.
you gotta click on the stupid image.
