I too, recently found out I am HPV+. My husband and I have been married for 26 years, both of us have been faithful. However, we were not virgins when we married. This virus can lay dormant for years plus your own body at times can fight it off but it can also reoccur. There are many strains of HPV, some you will develop genetial warts others are the precurser for cervical cancer. Before you go for your consult with your nurse write down your questions and take them with you. Ask her if they know what strain you have.
You should tell your husband you are HPV+. You said he has been unfaithful in the past and you feel this is how you contracted the virus, if so he is a carrier and needs to know.
I had an abnormal pap result recently (ASC-US) and had a colposcopy/biopsy done last Monday and I am still waiting for the results. The Dr. said I would spot for a few days. I cramped and spotted for six days. The biopsy for me wasn't too bad, a lot of cramping, just remember to do your lamaze breathing during the procedure. Also, do a search on the web for HPV and read and learn as much as you can. You will find out you are not alone with this.
Good luck to you...
