Is promiscuity wrong or the way we are meant to be? I would say that it's only wrong if it gets you into a lot of trouble and we do assume that if you're promiscuous, you will get into a world of trouble and hurt. I also believe that it's the way we are meant to be - but social norms have other ideas about that. What I know for a fact is that being promiscuous has gotten me laid... a lot. Promiscuous as the day is long... but never stupid or careless and therein lies the difference between the best way to be and the worse mistake ever made.
Depends on your upbringing. I was raised in a very religious household. Hell when my folks married, my mom was a 28-year-old virgin. Dad said she wore him out on their honeymoon. My wife did mention our first date sex, but after our first MFM with my buddy, she asked if she acted too slutty? I said she acted like slutty was a bad connotation. I told her I loved how she let herself enjoy the moment. She liked my response, and here we go again. I loved my “slut” wife! Wish she still was!
I'm right there with you. My wife and I are both in our late 60s so, due to one medical issue or another, our "slutty" days are behind us. However, if we were still in our 20s, I'd like my wife to have been two to three orders of magnitude sluttier that she was. That includes her wanting to make sure that me and several of our close male friends got as much sex from her at they liked! (I got her to provide all the sex that one of them wanted, but that was it.)
