All Three (take 2)

Josh has always been a fan of futanari, but not so big a fan of hyper-size, so when he started to muck around with the settings, the end result reflected his biases.

A gender ratio of 30% male, 40% female and 30% futa.

Average penis size for males and futas of 8 inches, with 90% being between 6 and 12 inches.

Average ejaculation of 5-8 ml.

Cervix contact (and penetration) is pleasurable.

It's uncommon, but not exactly rare, for women and futas to orgasm just from penetration.

Vaginas and anus are elastic enough to accomodate all penis size (barring enormous outliers).
