hi, having recently had sex quite a lot, for the last couple of days i have found that having sex with my girlfriend, or any from of oral sex has really hurt my banjo string, even just puling back of foreskin. having had a look today, two parts of it have swollen, one on the bellend and the other further down, looking like two spots. is this anything to worry about, will it go away if i leave it a few days?
