When a woman loses virginity,how much blood comes out during break of hymen?

Nowadays, with women so active in sports and other physical activities, there may be NO bleeding. The hymen could have been broken previously in natural ways.

The wedding night proof of virginity (a bloody sheet) is an ancient myth.

What is the "proof" for the male's virginity?

I am not talking of purity.. actually I wanted to have sex with my virgin girlfriend... in my home... so will that blood coming out spoil my bed sheets?. I will have to wash the bedsheets then bfore mom comes...

She may bleed very much or she might not bleed at all.

Put a large waterproof pad under her and you.
