I am a 17 year old girl and have a higher sex drive than my 19 year old boyfriend. I know its normal for teenagers to have very high sex drives but mine is off the charts. I cannot control myself when j feel the urge. I masturbate on avrage of 5 to 7 times a day. A few times ive gone 13 times. I also have sex with my boyfriend quite often but even after we have sex i still have the urge.my boyfriend cant keep up and im worried i might be a nymphomaniac and will end up doing something i regret because i have no controlover my urges. Please help!
