I am about to turn 19 years old. I started masturbating when I was probably 11 years old, but since two years maybe I started masturbating excessibely (once or twice a day no days off). Sex before those two years was great, good long erections as soon I was with a girl, even if we just touched or kissed .. but recent sexual encounters have been a dissappointment as I havent managed to get a full erection and I even couldnt penetrate one girl I was with a couple of months ago as my penis would just erect, even if the girl touched me, we kissed and she was just naked in front of me(even girls I knew were hot). I even tried to concentrate to get an erection but couldnt. Sometimes I was alone masturbating and could get a full erection, or even after wakin up. But I dont really think the problem is that I just feel nervious or sth like that, It must be sth related to excessive masturbation, as I have a really healthy lifestyle (workout, eat healthy food, sleep well most of the time) . I decided to completely stop masturbating and this is my 3 day without doing it. Id appreciate if someone could help me with this as its really affecting my sexual life, even life in general.

Thanks for the additional details. Usually, but not always, if a guy brings himself right to the edge, but just stops short of ejaculating, he can maintain an erection and continue either to repeat this process of stopping short, or just go ahead and have an ejaculation.  You are fortunate to have the capability to keep an erection after ejaculating as most guys do not.  That is why it is perplexing to hear that you now lose your erection after bringing yourself to the edge but not ejaculating.  To answer your question more directly: with most guys, having sex or masturbating ending with an ejaculation almost always results in losing your erection.  For the most part, the effect is not the same if you have sex or masterbate and avoid ejaculating.  But, every guy is different and there could be other factors which are affecting your sexual experiences.

So I avoided masturbating for like 25 days and finally decided to do it, but this time I avoided ejaculating, and as soon as I did it I lost my erection and dont want to masturbate or have sex anymore. When I have sex or masturbate and ejaculate I always mantain the erection and even can continue doing it so this has me a little worried. Also, does masturbating or having sex and ejaculating have the same effect that doing so and not ejaculating? I refer to the fact of period of time needed to start having again really strong erections (as Ive been havin since I stopped masturbating)

You're on the right track by giving yourself a rest from masturbating. See how that goes.  If you have to, try doing it less often.  You may have to experiment to find the right number of days between masturbation sessions in order to balance getting relief while still able to perform when with a girl.  Hope this helps!
