I know a lot of the guys here are always trying to be discreet, I respect that very much.
As for me, I am single, and if I had a wife or GF I Would not be hobbying because I would be uneasy doing it, for me it's called respect.
When I go to a hotel or motel I do try to throw in that I am meeting my GF. The smarter agents at the places usually know what's going on, the ones who play naive are actually stupid and think that their places are 5 star motels at hotels I never had a problem.
I too try to always be discrete, but at times they do ask us questions and I do tell them that it will be my GF coming over, because I know the girls I get I always ask them to dress normally, you know jeans or tights, because I do not care what she is wearing because it's not the clothes I want to see it's her naked.
Just my take
