Does anybody know a way of lowering my sex drive as it's ruining my life, relationships an getting me in trouble?

Hi im a 25 year old male and i cant control my sex drive, i have been having sex since i was 14 and since i was 16 i have been having sex 5-8+ times a day, usually with only a few minutes gap inbetween an also masterbating (masturbating) 6+ times a day since the age of 9 and it's ruining my life.

It is cuasing my girlfriend pain, i dont think im big in the trouser department but girls tell me it's thick, im 9" in length an this doesnt help when im making love to my girlfriend as it causes her stomach pains from me trying to get as deep in as i can, it's also making me late for work, making me only get a few hours sleep a day, spend money i cant afford to waste and also im ashamed to say cheat.

I dont want to be like this but i cant help it, i try and restrain from sex an then i end up getting really horny while im out in public an gives me painfull erections, i have asked the doctor for help but they just keep offering me anti-depressant but all they do is make it harder for me to ejaculate which then that makes me aggressive because im as horny as hell but cant ***.

Also when i have had it 8+ times a day and masterbated loads, i still feel horny but only get a semi and then that makes me angry and my sex drive has caused me to have 3 kids with my girlfriend even tho she is on the pill.

SOMEONE PLEASE HELP ME!

You might want to ask your Dr to check your testosterone levels. They could be really high. If this comes back normal then another thing that might help is counseling to find out why you need so much sex.
