If you're a guy, why would you want to expose your SO to a mad world where people talk about jewelry all day long and debate about the necessity for More diamonds in their lives? I mean, just saying.
If you're a lady, do you want your man to know you're on a forum where people talk about... oh wait, did we just do this?
Mine knows, though I've never shown him any posts or threads. He just thinks I'm nuts. I don't get on his case about the hours & hours he spends on vintage racing forums, so we call it a tie.
No but I've told him about some of the more ridiculous threads as well as the ones I think he'd be interested in (like most recently the bar thread).
Eta: I just realized I did show DH one thread- one of the ones with pics of your Patek DF, and told him I want my own one day. Needless to say this forum makes him very nervous.
