Funny you should mention porn sites. I rarely looked at porn. It just seemed to boring or fake. I am on a few motorcycle sites where we share nude and semi nude photos and my wife enjoys sharing hers.
It wasn't until I discovered OCC that we both share things on here. It has changed our lives completely. So all porn and all women are not created equal.
Unless we are completely fooled and naive we've decided many things here are true life adventures much like our lives have been. It's fun sharing stories. We also understand how some wives are turned off by porn.
I was first introduced to porn by a very good friend while staying with him and his wife. In fact I was new to the internet and he was showing me things that are out there simply by clicking key words, like BIG BOOBS, or MATURE PUSSY.
I enjoyed looking at things he brought up and we saved a lot to a DVD for me. At that time I didn't even have internet. My wife also enjoyed looking. But his wife would leave ther room every time b*tching how perverted and nasty Jim and I were. I'll admit Jim is a pervert!

Here are two photos of my wife we show bikers on and off the sites. She is not a model and far from young. But we enjoy showing and many enjoy looking. That keeps us young.
I still suggest that you talk to your wives and let them know sharing her has been a dream of yours and you don't mind. But you'd like to know who and when and possibly be there. Don't be accusing unless you are certain.
