Slyar,
Please read my long post on the
Dull "Nice Guy" image killing me??
topic. Seems you have sort of the same problem. You have the confidence to talk to girls but did perhaps not build enough attraction and probably did not "kino escalate" (that means slowly starting to touch her more, read my other post). Building attraction well that is showing that you have humour, an active life, are well liked by girls (go out with them if your have female friends), can make interesting conversation, are a loving, caring person, generally show your value in an indirect way (show, don't tell), without trying to sell yourself like an ad.
Masturbation is a normal thing, just not a substitute and we know it. Let's get out there and meet some women, I need it as bad as you do. Am a 30-year old virgin, just a late bloomer I know I can change.
