I need help

I am a carrier of genital warts, and unbenownst to me I passed them to my boyfriend of almost two years. He began to develop warts about a year into our relationship, while I have not. I was vaccinated for hpv about 4 months ago to prevent the kinds that develop cervical cancer and such. My boyfriend recently had laser treatment for the warts. His doctor told him that I can give him back warts if we have sex again protected or not through vaginal fluid. I thought they were only passed though skin contact.
   My question is: can I in fact reinfect him with the same strain of HPV that he already has and cause him to have genital warts again? I've been searching and haven't gotten a definitive answer.
    Also: do the types of HPV that cause warts go away on their own through our natural immune systems like other forms of HPV do? Please help, I need definate answers. I don't want to put him through the painful process of laser removal every few months if I can even reinfect him...but I don't even know if that's possible.

Your vaccination will also provide protection against the types of HPV that cause 90% of genital warts.

While it is possible that your boyfriend's HPV infection was from you, it is also possible that it was an infection from a previous partner that has just recently become active.

You are right, warts are spread through skin, to skin contact, not through fluids.

Partners tend to share HPV infections. Many doctors don't see a need to drastically change sexual practices between partners as the infection is likely already shared.

Search through the expert (doctor) STD forum. The doctors there often state that partners do not "ping-pong" infections. You might be able to find some questions addressed by true experts that can help clarify your situation.

My understanding is that whether the warts stay away, come back, or increase or decrease in numbers is dependent on your boyfriends immune system. If you were the carrier, he would have been exposed to HPV many times over the course of your relationship. I don't think additional sex puts him at additional risk.

Furthermore, while you may have been a carrier at one point, there is a good chance that you have cleared the virus. After all, most infections are temporary and  you show no symptoms.
