There are no painful symptoms or signs of genital warts on males. They could make you feel uncomfortable when you are having intercourse, but then again with enough lubrication and moisture you may not even know that you have a problem at all. This can be treated but it is important to remember that all warts are from viruses under the skin and cannot be got rid of one hundred percent.
While females may not be able to detect any painful symptoms or signs of genital warts, it may seem different for males. Since the warts are more external than internal, they can be easily detected around and along the shaft or in the groin area itself. If warts had to be on the internal sections of the penis under the foreskin then painful symptoms or signs of genital warts would be obvious. It is unlikely and perhaps not possible for warts to grow under the skin in males if they have been circumcised. One can assume that if the male has not been circumcised then there is a possibility of having painful symptoms of genital warts.
Genital warts cannot be transmitted without skin contact, so using the same toilet or linen is still safe. But if you suspect more than just genital warts, avoid sharing anything that comes into contact with the skin. It is also a good idea to have a check up and be a little careful with the partners you engage with sexually.
A Vaccine Is Available
A vaccine is available for immunizing most of the strains of viruses that cause warts, but not all of them are covered, so it is still safest to say that abstinence and or safe sex (not random partners) goes a long way in prevention rather than finding the cure, because there is no permanent cure for warts of any sort.
Expectant mothers who are about to give birth stand the chance of passing the virus onto their babies via the birth canal, to avoid this your obstetrician may recommend you have a Caesarean section if you wish to avoid this implication, or you could have laser treatment or have them burned off if they are external before the baby is born if the obstetrician says it is still safe to do so, otherwise as soon as possible after the birth.
