When I came out as bi to my wife it started a greater conversation about sexuality, past experiences and our desires. She has a very strong desire to please people. Making people happy actually gets her off. So, if she can use her sex to make people happy...we all get off. We also discussed the fact that there are certain things that I cannot do for her sexually. I have an average dick (6.5") but with her amazing ass, doggy style can be a little challenging sometimes. She likes it hard and deep from behind. So, enter the guest cocks. Additionally, she never had a "slut phase" in her 20's like a lot of us do. We started dating when she was 27 and I was only her 4th man. Now, into her mid-late 30's, she is at 18 men and loving life. She will say that at times it can be a bit exhausting trying to maintain multiple "relationships" but for the most part we really enjoy the lifestyle. We have made some awesome connections, men we still consider friends, and some connections that were absolutely just one and done. I would appreciate a man that wants to be more than just a fuck for her because I do not think that two people can be "everything" to each other. Having another man to be a part of our lives and give her (and me) things that we can't give each other is what the lifestyle is for us. We've been together 12 years, married 10+ and open for 8+ and no, we are not going back.
So to make it clear for those who haven't: The "timer" was a separate applicator you would put on the trigger where the photographer would normally use her/his finger. It was an external mechanical tool that would "simulate" the photographer's finger, so to speak, but with a time lag after one had pushed the button. May seem funny today but it actually worked.
