There are several that are not harmless, especially for women.Genital warts can indeed cause problems for women, the worst of which is the fact that it has been linked to cervical cancer.
Very little is known about HPV by the general public, in fact recent studies suggest up to 80% of sexually active people get HPV (thousands of whom visit this site everyday to find each other). Most people think sexually transmitted diseases will 'happen to someone else' or that using a condom is 100% foolproof in protecting against STD's.
Most just aren't aware because they are asymptotic and continue about their lives without ever even thinking they could be spreading a potentially deadly virus. The most important thing to realize is that ANYONE who is sexually active has an extremely high likelihood that they will come into contact HPV.
Once you have had it, you will always carry the virus, but it is very uncommon for you to ever give it to anyone else ( unless during the initial outbreak )..of those things that we just always carry around with us.
It is spread via direct contact..like herpes, and can be spread to any part of the body, not just the thing that has not been mentioned yet and in my opinion the most scary part.
(Yikes..insert awkward pause in dinner conversation) How easy do you think its going to be to find someone who'll understand and accept you now that you're "damaged goods"?
