Hi I've had a problem with bacteria vaginosis previously and the last time I saw my doctor she said it was gone. But now I think it may be back and now my boyfriend is getting a rash on his penis. I've been looking up some things and I saw something called blanitis. Could I have caused this in him? Also I have never had this problem until I started having intercourse with him. He is the first guy that I have been with that is uncircumcised could he have caused this in me?
