I suggested trying it with a woman years ago and she gave it a shot. When she was done with sexual pleasure for herself, she made the suggestion that I should try it with our old gay friend , who was as desperate for sex, as much as I was. Since I enjoyed anal toys and self cum cleanup in our past, she tried and conviced me to try it, as I promised her years ago. She doesn't consider it cheating, because she knows. At our age(70s) it really didn't matter anymore. I have to thank her, for giving me the opportunity to explore something other than my hand. Are you fortunate to have an open minded spouse.? If the subject never came up, how do you think they would react?
Mine is open minded more even than I am. I took her up on the idea and she was not really keen on my SO being a woman. I had performance issues, but I found out how much I liked cocks, only for sucking and pulling. I had an old gay cock sucking guy who serviced me and I got to like returning the favor, even if he only had a 2 inch dick.
I doubt my wife would ever suggest it, but an old girlfriend was fingering my ass and asked why I didn't find a guy to fuck me.
My present wife is very open minded far more than my previous wife. We enjoy regular bisexual activities with another m/f couple, he and I have several others we suck off regularly as well, and she is working to add another woman within our bedroom as I type this. My wife at 63 doesn't desire sex as much as I do at the age of 59 and is very happy that I've had a regular guy for mutual oral the past 13 years because she's stated, "I'm not able to provide 2-3 blow jobs a week, so you guys have at it" and when I'm in the mood just be ready which I always am. My wife wants me to be sexually satisfied knowing I have sexual desires needing attended to and wants them being satisfied as long as I do not neglect her needs when she is in the mood which I never have done nor ever will.
