Hi, my husband and I have have been married since 8 years.Since the past one and a half year, he has started having blisters on the foreskin of his penis every time, we have intercourse. at times, there have been many blisters. we have been abstaining for months. For some months he didnt get any, then he started getting the blisters again - one or two now. the foreskin seems dry. we were thinking if he needs to be circumcised
