Hi Patrick ~
Being exposed to something and actually having it are two different things. Just because you may have been exposed to the possibility of contracting the virus doesn't mean that you did actually contract it. Have you had genital warts show up at all? If you have then you may want to have a doctor take a look to make sure that they are indeed HPV. You almost have to have some type of symptoms in order for a doctor to tell you if you have HPV since it's difficult to test men for this virus.
As far as having a discussion with your future partners, I see nothing wrong with discussing std's before sexual activity. You could even take it one step further and make a date to go and get tested for all STD's. But, if you do that make sure you find out what you are being tested for because not all clinics and doc's offices teste for everything.
Good luck and I hope my response has been helpful to you.
