Does he have any sort of STD?

Okay I have a boyfriend. We've been dating for 7 months now. I seen his dick. He had 2 wart type looking things on it. It wasn't big. But it wasn't so tiny that you had to look closely at it either. Is it something I should be concerned about?? There was also a sorta reddish tone too the part closest to his crotch? Sorry for poor labeling. :p
