[also added by me] I have had sex since I was married. Many times. With more than one person (with full knowledge and consent of all parties), although not at the same time. I used birth control every single time. And I'm not sorry for any of it; this is perfectly reasonable behavior if you happen to be wired for or open to polyamory or swinging. (I'm much closer to the poly end of the range than the swinger end, but that's just me.)
[returning to the original] Any politician who voices the slightest problem with this will not be getting my vote, my money, or my effort. Voting for someone who holds you up to public contempt is self destructive.
