Some Adults
There are also some adult men in whom ejaculation does not occur until a few seconds after orgasm, and for whom both experiences thus remain completely separated.

Some men claim to have trained themselves to experience multiple orgasms while being able to withhold any ejaculation. In other words, for them orgasm and ejaculation remain two separate phenomena. This is said to be achievable through deep breathing throughout sexual activity. Usually, as sexual excitement mounts, breathing becomes increasingly shallow. By going against this "natural" tendency and deliberately maintaining deep breathing throughout, these men claim to achieve several orgasm without ejaculating.
