Your perceived lack of sex drive has nothing to do with your masturbation as a young person. You are still masturbating 2-3 times per week so you indeed to have a "drive" for sexual release. You not being interested in girls is also a completely separate issue too. Nearly all men masturbated and young people and continue to do so well past 26 and have girlfriends, boyfriends, wives, lovers, mistresses and every other kind of relationship you can imagine. You aren't sexually broken or masturbationally challenged. You are just antisocial. If you are really worried about having what other people consider "normal" relationships, you should talk to a therapist who may help you find tools to be more social.
