There can be a malfunction where semen is ejected without the accompanying sensation of orgasm, although the term usually refers to a man who ejaculates quickly after the start of stimulation, and has no control over it.
The answer is, yes. A man does in fact have an orgasm when he ejaculates prematurely. There is a solution to this and I have provided a link to what I think is the best possible solution. Lexaryn is a pill that a man can take and give him the ability to hold an erection longer and increase sexual pleasure overall. Their website has much more information than I have given here. You should check it out if you are interested. Media URL: http://www.lexaryn.com Description:
