If a couple who are in their 70s and 80s are in a romantic relationship how do they introduce their romantic partner to friends? The couple are not living together, but are having a sexual relationship. Boyfriend and girlfriend doesn't seem quite right for that age group.
I've rejected:
Partner (could be a business partner)
Friend (doesn't take romance into account)
Friend with benefits (too much information, and doesn't take the romance into account)
Paramour (would send some people to the dictionary and it's more applicable to an illicit relationship)
Lover (too explicit)
Manfriend/womanfriend/ladyfriend (nah)
Life partner (might imply they are living together, and 'life' at their age would probably bring on a smile)
Companion (could be a paid companion and not a romantic partner)
Mate (nah, could be a workmate)
Any other ideas, or should I stick to boyfriend/girlfriend?
