To clear some things up....
Genital warts come from any kind of sexual contact with an infected person, doesn't matter if the guy is wearing a condom or not. To make it worse you can catch the virus even if the infected person doesn't have visible warts as the virus lies under the skin and any kind of contact can pass it (and it's possible to have the virus forever without actually having any warts). I think it's something like 1/5 people have it, so basically if you're in any way sexually active it's fairly likely you'll get this virus.
