I find it sad that someone is concerned about the lack of a sex drive at age 14. What pressures are put on young teenagers nowadays... It's no wonder to me that anxiety & OCD are rampant in people under the age of 21.
I know there's no way to go back & regain a more care-free childhood - - but I'd sure try to if I were you.
Back off on heavy sexual relationships. Back off of alcohol - if you can - and if you really can't have a pepsi when other's are drinking then work on that!
Concentrate on your studies (I know I sound like I'm 100 but trust me, this is Life 101) and throw in some volunteer work if you have a few extra hours a month.
And do keep going for counseling/meds for the OCD.
But re-think your priorities for just the next couple years.
Simplify.
