Thinking more about the mismatched definitions thing: In matters sexual, especially, I'd say it's important to not be misunderstood.
E.g. in bdsm contexts it's not unusual for one person to help/make another person orgasm, while person 1 has all hir clothes on and has allowed no touching of erogenous zones. This may well be the negotiated arrangement between person1 and person1's SO*
If person 2 then mentions to person 3 that sie had sex with person1, that's a) inaccurate, as far as the vast majority of the population is concerned, b) bringing a far different idea to person3 of what happened between 2&1, and rather importantly, IMO, likely to cause major issues in the relationship between person1 and person1's SO.
*for both safety and legal reasons, this is also quite often the setup a prodomme uses.
