Me and the Mrs never take sex in the bedroom seriously . Thats probably why we do roleplays as well.
The only time we took sex seriously is when we were trying for our son and she had charts and temperature guages of which I shredded and discarded shortly after their introduction but thats another story .
One of the maddest things we have done is chase each other around the bedroom each armed with a paddle . After 15 minutes we count up the number of hits scored on the backside of each other and the loser faces a forfeit . The loser is tied up and "teased" and becomes a sex slave for the night .Sometimes I have to wonder if my Mrs loses on purpose !
I know its mad but fun at the same time but that just sums up us I think .
