Being so much of a virgin, you contract virgin disease. This makes even others susceptible to becoming a virgin just by being near you.
It is said to have stemmed from the biggest virgin of them all, an Indian named Reece who likes to play S.T.A.L.K.E.R and Rising Storm 2: Vietnam
Philip: Man, you're such non-virgin Ethan!
Ethan: Thanks Genius Phil- What's that. Oh shit, that Indian man Reece. He has Virgin Disease. We better get out of here before we get Virgin Disease!
