It's been proven even on anonymous surveys women play down the number of anything sex related and men exaggerate. So id expect these numbers in reality to be even worse.

Proof:

The study says women 'forget' partners, add years to the age at which they lost their virginity and refuse to tell the truth about masturbation or using pornography.

TLDR: women lie even on anonymous surveys, just in case they get caught out.

Lessons learnt: Don't marry. If you insist on getting married. No hymen no diamond. Why risk 70% of your current and future worth on a second hand car.
