I'm 18 and normally I can mastrubate once a week and be fine for awhile and not have any "urges", but lately I have been so aroused that I mastrubated twice in one night and then again the following morning, and I've still got the urge to want to continue... I've already gone through puberty so I don't believe that's the cause, but I will say all of this arousal is getting really annoying... Why would my sex drive be significantally higher than usual and is there a way to get it to decrease?
