Keep in mind that 80% of people will get HPV in their lifetimes. I know that's a staggering number, but it means that HPV is just pretty darn hard to avoid.
Think of it as the common cold of STDs.

HPV is a complex topic and unfortunately there is still much confusion about it. It's really not possible to know when you were exposed to the HPV virus. You could have had it for years and it just caused changes in your cervical cells. Usually "high risk" strains of HPV last longer than "low risk" strains, which usually clear within 8-10 months. It's hard to say how long you will be contagious to your current partner. It's also possible that he already has the virus and transmitted it to you (he could have had it before you became sexually active, or you could have had it prior to this relationship). Trying to figure out how you got HPV is pointless-you will probably never have an answer. HPV really has nothing to do with his PSA results. Generally, the HPV virus does not cause any serious complications in men. My advice would be to follow up with this and keep getting regular PAP smears. Your HPV virus will probably clear on its own and no further treatment will be needed, but you need to keep getting regular PAP smears to make sure this is the case (your doctor might suggest every 6 months instead of yearly to track your progress). If your PAP smear does not return to normal, your doctor will discuss the best treatment options with you.
Good luck,
