 Just my opinion...
I recognize that everyone's view of "swinging" may vary, and also the degree or method in which they participate in "lifestyle" activities.
Even so, it just seems to me that what you have described is actually more properly termed "dating". Except that dating for singles can mean there is some "future" to it. I assume the "dates" each of you might have would be informed of your married status.
I believe that successful lifestyle ventures begin as discussions of desired shared experiences as an enhancement of an existing, established, excellent and adventurous sex life.
It sounds like there is open communication between the two of you, since he openly stated his desires. No one else can determine for you whether or not this type arrangement will be successful and not harmful to your marriage. |
