We are a mid 40's couple that has been married 10 years.  We have in "my opinion" been unsuccessfully swinging for most of our marriage.  My beef with our current situation is my husband doesn't interact with me at all when we are swinging.  It seems that he can't wait to be with someone other than me, although he tells me that I am the best sex he's ever had and I hate to admit it but from what I've witnessed, I would have agree.  I personally don't understand why this is such an obstable for him, isn't swinging about "group" sex?  Isn't it also about creating an atomsphere that "everybody" is enjoying the opportunity to interact and lastly, and possibly most important,  isn't it suppose to be about creating an environment that promotes spousal fulfillment?  I've tried more times that I can count to discuss with no success.  Am I totally misunderstanding the situation?
