Yes possible: Sexually transmitted diseases (STD) includes a variety of infectious agents that can be passed on from an infected person via various exposure routes. Most of the time, people do not know that they are infected until they are tested or start showing symptoms of disease. The visible opening of the penis is a mucous membrane and can harbor transmissible STD. If he is known to have a STD, get tested
