A total lack of ejaculation-be it via masturbation or intercourse- can have serious bad consequences.
I read an article in a med mag about these men who allowed themselves to be totally controlled by a women (spouse or otherwise). One guy in particular, obeyed his "mistress" and did not ejaculate for 6 months. After a bit of ache and pain in his crotch area, he went to a Dr. It seems his prostate had developed an infection of some sort because of absolutly no ejaculation. The Dr. did a prostate massage ( I can't remember if the guy stroked or rub himself at the same time or not) but when he got close to cumming, he all of the suuden screamed in agony as he came. Seems that there was a lot of other factors in the body. The tubing from the prostate had not been stretch or whatever for all that time.
As well as the muscles used to cum had not been used.
report finished to say that the physical and psychological consequences of self denial aren't good.
When one denies oneself of it, it ends up being the only thing they think of.
