My exwife screwed many of my friends and she was vocal about me having a little thin cock. she called it a pencil dick. We enjoyed our time together and had alot of fun but she had very little interest in me sexually other than she thought it was funny how hard my little cock would get when I would be teased by other guys. It was a huge turn on for me to be around guys that knew they were giving her a nice thick cock because I could not.
My wife now was a virgin when we married so she did not know any better. She got to experience the thick cock of a close friend that brought her to orgasm that I never could. She has never looked back.
Very similar situation for me. My wife has referred to my dick as a pencil dick, too, lol.
Sorry your marriage didn't last. At times, I am amazed my wife and I have survived for over 30 years.
Our best experiences have been with live-in lovers. So, more along the lines of polyamory. However, it can be difficult to find the right kinda guy to be my wife's live-in lover.
When I was a pilot in the military, there was never a shortage of single guys in my flying squadrons. We would have squadron parties where the wives got to meet the other wives as well as the single guys. My wife called it the meat market, lol.
My wife would get to know these single guys enough to where she could identify one, or two, as good candidates, lol. This was fairly common in the military, so we were not the only married couple shopping for a fuck buddy for the wife. The single guys knew this and most were very open to fucking the married guy's wives. These single guys had no desire to get married, but liked the idea of having a married woman for regular, consistent sex, instead of having to date and chase single girls that could eventually want marriage.
If it worked out well, which it did several times, we would offer to let my single buddy move in with us. We would tell the neighbors we were simply renting a room to my single squadron mate. In reality, the three of us were sharing one bed.
Obviously, part of the criteria was that he needed to have a nice, big cock and know how to use it, lol. If so, I liked letting my buddy become my wife's primary sex partner. I got all the sexual satisfaction I needed watching them and doing clean-up.
Part of my arousal is denial. So, I can easily go months without having sex with my wife, while my buddy fucks her everyday, multiple times a day. Plus, I love knowing my wife is carrying another man's cum inside of her everyday, instead of mine, lol.
She preferred having sex with him, as well, so it worked out for everyone involved.
