When you say ejaculate, do you mean have sex, or do you mean even ejaculate by masturbation?
Is it just an urge, or a compulsion? What happens if you don't find an outlet? Can you just masturbate?
A few weeks isn't a long time, medically or socially. Do you think this could be psychological? While the experience of sex and masturbation are very different, a lot of the same hormones are released, so masturbation should help ease some of those feelings.
Do you do anything harmful, to yourself or anyone else, if you don't get to have sex?
Hi: Everyone is different in terms of their needs, wants, and desires. There is no particular amount of time between ejaculations for a guy that could be considered right or wrong--or anything in between. I myself find that about 2 to 2 1/2 weeks is about all I can go before feeling the need for a release. It is not always necessarily feeling horny that makes me want to ejaculate. Rather, a guy's glands fill up with seminal fluids and this fullness is what can make a guy want to get a release. He may begin to fantasize about a situation where he could get a release, and this fantasy could then make a guy horny. But, again, there are also guys out there who are horny almost all the time--even though they may have ejaculated the night before. I view my situation a need rather than a want after those couple of weeks. Hope this helps others who may be reading this question.
