Jokes never go over well with my wife, but at least I'm getting the sex life I would like.I know what you mean. I've joked about some risqué things but even the jokes weren't meant with any good response so I knew anything more would be too much.
I did suggest we get a boat and we could go out and be naked in it and have all kinds of fun and then for three days after that I took a beating for suggesting buying a boat! Not as much the sex on the boat but the boat itself! I then said we could rent a boat instead and her reply was "I'm not talking about this dumb idea anymore". So needless to say that idea didn't "float".
I am sorry to hear that about your boat idea getting wiped out.
