Hi Toufik, Welcome to HealthcareMagic Forum.
Are you sure they are Warts
or are they Pimple like things? If you have had Unprotected sex recently may be you should get a Blood Work up done to rule out if you have any STD
. Until the cause is found out and treated, they will keep appearing.
Kindly consult a Urologist
so that he can examine you and come to a Final Diagnosis.
