I've had unprotected sex with someone a few times in the past 3 weeks. Just today, I saw an unopen canker sore like scar on his penis that was never there. Also, his penis was pretty pink. Also, there was a little extra skin (bump) on his penis right under the head. He also said that he didn't take a shower for a few hours after we had unprotected sex. Also, I've been feeling this tingly uncomfortable feeling near my anus for a few days. Is this herpes?
