genital watts

Can humping lead to genital watts? I know someone who had a sex partner and the guy had been using condon but she still had genital  watts. So what would have happened?

If this was her only sexual partner and she knows this is the source of her HPV warts. There are a few ways she could have gotten them.
1. Condoms are not 100% so if he had infected skin not covered by the condom that touched her gential (genital) skin there is a risk.
2. If they had direct skin to skin genital contact either unprotected sexual or grinding without clothing.
3. If either of them touched his penis then her vagina with the same hand and one after the other. This carries a small risk but still a risk. The other two ways are much more likely.

The ways to prevent this is, not having sex, using a condom even if it isn't 100%, no skin to skin contact (keep undies on) and washing hands between touching yourself and your partner.
