its probably your current girlfriend's vaginal area that is emitting the fishy odor. force her to take more frequent showers/baths that should definitely solve your fishy smelling penis problem.
fishy smelling penis. ever since i started having sex with my current gf i notice a really bad smell from my penis. there is no rash or sores or anything so i don't think it's an std but what could it be? how can i get rid of it?
