I was discussing Blush: The Card Game with someone the other day, and they asked me what the difference was between ejaculation and orgasm for a person with a penis. The difference is a little more obvious when the person has a vagina – and for most people, more difficult to achieve!
Orgasm is a rhythmic series of muscular contractions that are pleasurable. Ejaculation is the release of fluid, usually at the height of orgasm.
Each can occur without the other, and intercourse can happen, and be enjoyable, without the occurrence of either.
