Hi. I Was Wondering If You Could Tell Me Why

Hi. I was wondering if you Could tell me Why my penis smells funny. Kind of like a vagina? Also, under the foreskin, right below the head, the skin is witeish in color and wipes off if I wipe it with a cloth. After I wipe it, it looks a little irritated, but I'm not sure. My girlfriend is clean. She doesn't have anything. But she didn't realize she was on ther period. Would that have caused it?
