Welcome to our Forum and thanks for your questions.  I’ll be glad to comment.  Were the lesions that were noted treated?  The reason I ask is because appearances can be deceiving.  There are many benign dermatologic process which can occur on the penis/foreskin which can mimic warts.  At the same time, the fact that your lesions grew and another one appeared is certainly consistent with HPV/warts.

I presume that you and/or your wife may have had sexual partners before marriage.  If so, you are both likely to have acquired HPV at some time in the past.  Over 80% of sexually active persons will acquire genital HPV at some time.  For most people these are innocuous problems which cause no problems although, particularly for women, a very small proportion (1-2%) can be present and lead to abnormal PAP smears- it is for this reason that regular reproductive health checks are recommended for women.  There are many different types of HPV.  Two types, types 6 and 11 cause over 90% of visible genital warts, as well as many clinically inapparent infections.  Once a person has HPV, lesions may occasionally appear years after acquistion of infection.

The bottom line here is that visible genital warts, if that is what the lesions were are an innocuous process which have little or no meaningful significance to you, or your wife’s health.  (BTW, if your wife had the HPV vaccine at some time in the past, this would virtually eliminate her chances of acquiring HPV 6 or 11 from you).  The appearance of a visible wart absolutely does not suggest sexual infidelity in any way,

I hope that this information is helpful.  If there are other questions or any part of my reply was unclear, you have up to two follow-ups for clarification.  In addition, the sponsors of this Forum, The American Sexual Health Association, have an excellent discussion of HPV on their web site.  EWH
