For us, absolutely. For you or anyone else...it's not a simple answer because swinging isn't for everyone.
Mrs. Diggs and I love each other very much. After 14 years together we still have a very romantic love and most importantly there is a lot of respect for each other. Almost everyday something happens where I tell my wife how much I appreciate the things she does, puts up with, etc. or she tells me how happy she is that I'm her husband. We work hard to never take each other for granted so when we first started talking about the lifestyle we spent a lot of time on "why" we would even consider having sex with others.
For me, as a guy where sex is really a physical thing. I believe women are beautiful and there is something fulfilling for me as a guy when I have sex with someone new that has nothing to do with love as much as with the appreciation of enjoying an experience with another. The different style of kiss, touch, taste, etc. is erotic and stirs sensations that just don't arise when having sex with my wife. It's not better, it's different. My wife and I share an intimacy that can not be replaced nor would I ever want it to be. We connect on so many levels beyond the physical.
For my wife, she enjoys the sex but for her it's more about the emotional foreplay that leads up to the sex. The sex is just the natural conclusion of an erotic evening. She loves the stimulation of someone new finding her sexually attractive and beautiful. She loves the feeling of being desired and the raw passion that arises from someone new. Those lustful feelings that have long faded (replaced by something deeper I'll add but faded none the less) in our relationship. What she often describes as the best part of an encounter...using her words is the "intensity" at which the other person has shown towards her. That "I'm so into you that I have to have you now" type of intensity. That is what she gets out of it and what she enjoys.
When we both leave a play date and we are headed home with that content smile and she says something silly like "We really have the best of both worlds" meaning a committed relationship and the raw passion of single sex...and she genuinely asks if I had a good time and what I liked best and what was my favorite part. We build new bonds through that shared experience and we laugh sometimes and we learn sometimes but ultimately, it was a shared experience no different than us going to a park together or going out on a nice date together. We did it together.
There are many people that get into the lifestyle for the wrong reasons or they can't handle the emotional turmoil it can create. Swinging takes two people who can compartmentalize sex. My wife amazes me that she can enjoy sex and simply walk away and say, "that was fun" like we went bowling. I think that is why we seem to be doing so well in the lifestyle but we have seen it take it's toll on others. We have seen maybe five splits between couples we have met over the past three years (almost three). So is it worth it...if you have the honesty, trust and respect in your relationship to say something even if you feel it may hurt their feelings(because that's the amount of honesty I think it takes)...it's worth it.
