Red Spots on penis and itching after sex

Hey, first of all thank you very much for answering my question.
I m 25 years old and of perfect health.
I have recently have a girlfriend and I slept with her various times without protection (she is using a ring) and I realized that after the sex I have got red small spots on the penis head and also it seemed itchy. I washed my penis deeply since then and after a couple of days the red spots dissapear again. But then when we have sex again the red spots come back and it is also starting to itch a little again and then after a couple of days (not having sex) they dissapear again. I was wondering that it maybe has to do something with the ring, can you get rashes from that or can you actually be allergic to it?
I dont know what else it could be because I never had this before.
Please advise me
