Hi. My boyfriend has always had this small mole-like spot on the left side of his penis, however, over the last month, I have noticed it has been getting bigger. He said it's not painful to touch or doesn't physically hurt when we have sex. However, over the last month, his sex drive is low, he's always tired, he's been getting this rash in the groin area that sometimes smells fishy, and the past couple of times we've had sex, he's complained that it hurt to orgasm. Not a burning hurt but like a super hypersensitive hurt. What could be going on?
