Doing the deed. Getting set. Having sex. It appears as if every euphemism for intercourse suggests an action. (and I also simply looked at a different one: find some action. No ambiguity here). Which is because intercourse is basically considered a physical exercise, though it certainly are as much a difficult undertaking because it is a real one. Intercourse is intimate much more means than one, and that’s why, whenever a partner is unfaithful, your room activities might suffer because of this.
