hi, my girlfriend and I, about 6 years ago, were up to no good and she put a rubber band around the base of penis. Unfortunately, this was left on overnight and am wondering if this has caused permanent damage? I get weaker erections, it has to be constantly stimulated for it to be maintained, if I stand I kind of lose it, I do get erections in the mornings but don't fell that I have the same erections that I previously have experienced. My ejaculation use to shoot out but now only experience dribbles. I am also experiencing pains in perineum and around buttocks but that could be as a result of pelvic floor problems too.
