I'm 30 female.

My boyfriend recently has had problems with the head of his penis being irritated only when he gets an irrection. It's never red or irritated but feels what he describes as painful only when he has an errection. I asked him if it's painful when he urinates and says that only sometimes. I kind of think that this could be a uti but it's also just started to be sensitive since i've been using the nuva ring as a form of birth control. Any advise as to what we can do would be great.

Thanks!
