I mean, anonymous handles and no in-person (or zoom) chat might make that sorta possible, but you can’t get around the problem.
The real issue is that this is only a problem in one direction: nobody complains when someone says “my wife,” and some people definitely complain when someone says “my husband”.
It definitely gets made about sex, and gay sex specifically, by the people making the complaint. They’re the ones making it about sex and not leaving it alone as a conversation about one’s spouse.
