Please, give us a break. You contracted a STD, HPV, from your druggie ex, because you decided to excuse her poor behavior and sleep with her anyway. You walked into this one. The writing was all over the wall, and you foolishly decided to ignore it. You have no one to blame but yourself. Even now, you still get upset and defend her if somebody points out the facts. All I'm doing is saying what anyone with one ounce of common sense is thinking. Your rational thinking skills are very poor. Sorry to break it to you, but you aren't that smart.
OK,
HPV is a
VIRUS , in some people it causes warts, others show no outward symptoms, so simply looking at them will not let you know they have it.
Catching a Virus from anyone (if they never informed you they had it) is Never an indication of Intellect One Way or The Other. Don't forget all of the times , you accidentally passed a Flu or Cold Virus to someone else, either by a sneeze or other contact.
Because really, do you call yourself stupid every time you catch the common cold, which is a Virus.

FYI:
http://www.fitpregnancy.com/pregnancy/labor-delivery/ask-labor-nurse/hpv-and-vaginal-deliveryHPV is the #1 most common sexually transmitted disease and more than half of all sexually active adults between the ages of 15 and 49 have it and dont realize it. Theyll recover from it all on their own without ever having symptoms or problems or needing any treatment. The only way most women know theyve been exposed to HPV is because they develop genital warts or it shows up on their Pap Smear.
In rare cases, a pregnant woman can pass HPV to her baby during vaginal delivery.
