In my experience, single men generally don't understand what's really happening here.
I hear way too many -- "if your husband can't satisfy you then I can" and "can't we get together alone?"from single guys. I also have a problem interacting with many single guys -- a single (never married guy) just never seems to understand that paying the rent or washing clothes or cooking dinner or cleaning house are
really important.
Sometimes, I find that single guys are way too pushy -- it's all about
sex now! and rarely about
well what do you like? -- the number of "hey wanna f**k" I get from single guys I never saw before is astounding -- what makes a single guy think I'm a total slut or whore just because my husband and I share this lifestyle?
The simple matter is, we are
into sharing -- this is not about
get what you can -- now, I do understand that there are many women who are after 1:1 time and a single guy is an acceptable choice -- except that many husbands/SOs prefer that we women not get involved with single guys, to much chance of emotional attachments forming on his part. That
love word comes up with single guys too often.
Sometimes we just wonder "if you're such a great guy, why don't you have a wife or girlfriend" and if you have a wife or girlfriend but are playing alone then you are
cheating and most of us don't like that attribute in a mans character.
I am not "looking for love" and for the most part, no guy is gonna show me anything I've not seen before.

I'm not "a lonely housewife" or a "horny slut". But that seems to be the mentality of most single guys looking for playmates. My husband doesn't fail to satisfy me and your pecker probably really isn't "10 inches long and thick as a beer bottle" and if it is then please leave it in your pants around me. 10" is the distance from my elbow to wrist!
If you want to have a chance with a couple then there are some things single men must do:
* read about the lifestyle and begin to understand what it is
really about.
* never ever ever treat her like a whore or slut unless that is what she wants.
* never ever ever assume that you're "the best lover ever" -- you're a different lover who'se been invited to share. That's all!
* she probably isn't interested in falling in love with you and living happily ever after.
* if you're a homophobe then there is likely to be a problem -- when playing with couples, sometimes the husband will see your penis and you will see his

sometimes, they will even bump into each other....
Just a few of my thoughts -- looking forward to reading those of others.
