hand to genital contact is not considered a real risk for any std. we don't recommend any testing or any exams. plenty of prior posts on the std experts forum on this if you want to take the time to search through them to read.
have you had your gardasil shots for hpv yet while hpv is on your mind?
also fyi - washing up after sexual contact doesn't reduce your std risk. std's are transmitted during the sex act itself - they don't lay around on the skin to work their into the body over time.

I meant to say "low" before the word risk. It is low risk, but not zero.
Your hand to genital contact to yourself right after you fingered her was a risk to getting HPV. Warts may appear in 2-6 months after that contact. She should not have allowed you to do that with warts present. Some get them years later and some never get them at all but are still infected. Should you get warts, have them removed asap and then wait 6-24 months to not being infectious before having sex again. Most doctors believe the virus remains in your body forever but that doesn't mean you are infectious forever. 90% of the infected clear the virus in 2 years or less. There is no test for men (other than wart biopsy), so you will never know if you have it.
