Quick final question...If I was with someone that had visible genital hpv...and we had sex (unprotected)...and it's been a year later and I haven't developed any symptoms or any warts, is it fair to say I didn't catch the virus?
no, and even the chance he touch you, it is not a major concern as all warts are of the HPV virus. everyone will get warts at some point in there life. but the gential warts do not translate to the hands.
So unless he actually touches my skin, there is no need to wash my hands at all?
But is HPV not spread by inanimate surfaces?
Both and the glove idea also.
Is it irrational because of how long I wash my hands or because I do it after he touches anything?
I think you know the answer already. Irrational behavior. Are you seeing a theripst? If not I would suggest that you do.
