I feel itching inside of my penis. And when I itching my penis some white or grey fluid come out from my penis. But there is no foul smell or anything. If I don't itch I can see this whitish fluid inside my penis before pee. Some times this fluid just stick with my underwear unknowingly. Even I don't think about any sexual topic. When I pee some time I feel very little burning with my pee. But not every time I feel this burning issue. Please help me about this issue. And please tell me which medicine I should take to revive from this issue. please suggest me alopathic medicine.
