Welcome to the Swingers Board, Kitty2009
I don't think from the sounds of things you have any more issues than we do. We are tired and sometimes life gets in the way of (US). Especially trying to maintain a business, family, vanilla peoples drama..... Hell, I could go on forever. I for one, feel ya
It is true that Swinging wont fix a troubled marriage in most cases.
However, we at our age, need something to keep our sex lives stimulated. Without sounding like its a problem, one of the things that boosts our sex drives is swinging ! Its nice to get away sometimes and meet people that expand our sexuality. The thing is, good communication between ourselves was the key, in the beginning. I can see how you might not be able to find the right words. Do you have the opportunity for timing now ? Its as important as what to say.
I think you should ask your husband for a little time away from everything he is consumed with, if its the work load or just everyday life that has a hold on him. Start the conversation in a non threatening way, asking if he finds your relationship satisfying in every way. Its not selfish to ask our partners for something when we need it.
How much good quality time do you spend away from all of life's everyday same old, same old, now ? We have been together over 30 years, we do know we get in a rut sometimes...
I think your thoughts are valid

Our personal sex lives are vital !
Hopefully, with a little more insight, we may be able to help. As Swingers, we do promote a healthy relationship and life. Just being around people who share a good sexual outlook, does wonders sometimes.....
I could go on sometimes a bit too much, but its also about our well being as individuals. We share not only positive sexual stimulation with our partners, but playmates as well....
Talk to us, its a start

How do you really think he feels ?
