Because the question was asked elsejournal, and because defining words is good:

To me, sex is any activity which has intent for orgasm behind it.

This is often mixed up in my head with the parts of sex which involve sexual fluids and/or anal play, as that specific subset is simply the kinds of behavior which require a safer sex talk, in my world.

(I note that safer sex talk-requiring behavior also requires frequent enough interaction that I have and keep a sense of a person in my head, in addition to the right kind of connection and good trust and such)

Sexual interaction/behaviors is any activity which has intent for arousal, but which may or may not involve intent for orgasm.
