Sorry for the trouble that you felt ignored on this forum;it is meant for your help and i will try to do so as well as say sorry on behalf of our forum.
Since you have mastrubated in excess which you said there may have been some damage to the internal physiology due to vigorous mastrubation.Normally mastrubation does not cause any physical harm but in few people it may cause excessive dilatation of vein which can give rise to the pain during erection and if there have been a internal urethral damage due to any reason it may cause pain during ejaculation
The best thing in your case will be to consult a Urosurgeon and if he says get a cystoscopy
done to find some internal problem like stricture or any other anamoly.The cause should be found out so that you can be treated properly.Also you can take multivitamins and mineral like calcium tablets and stop mastrubation which you have already done.Consult the Urosurgeon and he will surely do the needful .
