Hi there

This weekend my wife and I played with good friends we have known for some time (let's call them K and L) and all 4 of us are in a group of approx 6 couples that all text, chat and meet for fun.

On Saturday night my wife was with K and I was with L on the bed and when it came to sex, I paused and wrapped up and all was good.

My wife and K were still making out and taking it slow. After some time, L and I retired to the kitchen and returned a few mins later and my wife was being fucked from behind by K.

All seemed well, it was dark and we had a great evening.

Turns out K wasn't wearing a condom and my wife didn't know until the end and she asked K about it later when they retired for water in the kitchen out of my ear shot and he basically said they don't use condoms with "regular and good friends".

He apologized and my wife was OK (sorta) and in the car home I wasn't angry or upset...

My point of this post is: How do swingers do the non condom thing. He (and I) have had vasectomies... but the STI risk? Do they just be selective with going bare and test regularly? Is this common? Is this level of risk "reasonable".

We see alot of bareback play or profiles that state that condoms are "optional". Whereas my wife and I are nearly 10 years in the life style and wouldn't dream of unprotected sex.

Are we paranoid? Are our friends nuts?

I am interested to hear from people like our friends who justify the no condom approach to the life style.

This is not a critical post, I am intrigued as to how it works.
