Hi, I've been with my gf for 4 years (I'm 22 male) and in these 4 years I've felt like 5 times (we have relations weekly at least) a burning sensation in my skin when we have sex and when I shower it hurts more, it's only superficial and then it dissapears, she goes to her gyno frequently and everything is right with heR, also she never has any discomfort. We didn't have relations in a long time because of corona and now (we've seen each other three times now cause we live in different cities) Everytime we have relations it burns a lot and she tells me my semen is pink, we have had to "do it" in a hurry so maybe it could be lubrication? Although she says she doesn't have any discomfort. She had a boyfriend before ( unprotected sex) me and i haven't been with anybody before, could it be an STD? we are rlly worried, there are no other symptoms whatsoever and it's been more than 5 years since she was with him. I rlly hope it's just my sensible skin idk, I appreciate any help. It's just skin irritation and the semen thing. Any opinion would be nice :)
