In my experience it spruces up the sex life tremendously! I hope your wife isn't in a refusing mood in the next while! It sounds like you are already accustom to talking about people that you are attracted to.
I find that there is little need sometimes to even sleep with others and in fact it sometimes takes away that feeling of anticipation and horniness. Prolonging that for a good long time can make the experience of being close to your wife that much sweeter and more intense. Not to mention when you sleep with the prospective secondary!
Building outside relationships can be so fullfilling to a marriage in that respect. I don't know why as a society we condone it so much.
