Have to agree that if that is your marital home, then it’s far too big a risk to take; she knows where you live, she knows you are married, she knows something that could destroy your life, she craves money. It really doesn’t stack up too well when you look at it like that.
To specifically answer your question, I would say that I enjoy outcalls at my place far more because it’s your own place and you can plan everything exactly as you like it and it’s actually quite exciting waiting for the door to go.
I would never entertain a WG for an outcall on a first meet. My ratio of outcalls versus incalls is around 1:10 as I need to build up some trust before I invite her to my home. Even then, I keep all valuables and personal items out of site. I also make sure she only has access to the living room, bathroom and bedroom.
In terms of privacy, I have an apartment in a fairly secluded area, but I am paranoid, so arrange daytime meets during the week when it’s particularly quiet. I’ve been caught letting a WG in on a couple of occasions by neighbours, but they know I’m a single guy and it’s not like she turns up to my door looking like a ho.
Walls here are quite thin here, so the tv will be on at a reasonable volume.
