What is really wrong with my boyfriend?

Hey doc! How r u? I know this question not really involve in this website. I just want to know what should i do. My boyfriend and I have intercourse on Friday,after intercourse he have a red bump in his penis(in the soft skin one).We do men on top position. SO we think is ok. Next day,we do it again and he get another one in the skin of penis that u can pull it down. When he wipe it,it kinda little bleed.So we didnt do sex for few day until Wednesday. This time we use condom in same position,when sperm come out he feel uncomfortable and it hurt like when we get a cut with lemon juice over it,that how he feel.And it get worst than last time. So next day we tried again but in the morning and without condom. With position came the back of me,do it for awhile then he turn me back do the same position. I ask him does it hurt...he say no,not much. He say he feel something in there,on the top. So, i really dont know what really happen. It that me or him. I ask to go check with doctor he say wait couple day if it not heal than go. So doctor and anyone know about this please help me what to do? Do i need to check pep smear again?
