They are rubbish in bed, but nice being the first.

What is nice about it?
No sexual diseases
Looks like overcomplication to me. Wanting virgins because they won't have sexual diseases? Most women don't have them. Virgins can have them too. How would you determine if a woman is a virgin? What about if she has SD?
Theres a couple of ways to tell if shes a virgin. I presume most men want virgins so they have women who havent been with others.
