Dear Welcome to HCM We understand your concerns I went through your details. I see that you are under treatment for schizophrenia. Even then there is minimum possibility of lack of ejaculation. Retrograde ejaculation , as its name implies, is a condition where the seminal fluid is ejaculated backward (retrograde) into the urinary bladder instead of forward. This usually occurs because the neck of the urinary bladder, which normally closes to block such retrograde flow, is unable to do so. Such inability usually results from neurological or physical damage to the bladder neck, which in turn can result from a variety of clinical conditions. I suggest you to consult an urologist for further investigation and advise. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
