i don't know. i never had the opportunity to reach a personal limit (which in most cases is considerably less than what your mind creates). sex like any physical activity can border on being addictive. i have known runnersand cyclists that were so addicted to the high from running/cycling that the could not stop even for a day. if your sexual activity is interfering with your daily activities or the activities of your partner(s) then it could be a problem for you. people can be obsessively hypersexual for sure like a nymphomaniac. if your hypersexual activity is risky (multiple partners unsafe practices etc. ) then you may need some professional help. if you are just having a active sex life with a willing partner then consider yourself a very lucky person.
is it possible to have too much sex?
