Why?

I have never measured my cock. My girlfriend wanted us to. I loved the idea that we measured 6 and a quarter to her exs nine. This isn't a fantasy. I've seen pictures she's kept. Pictures of her sucking and fucking it. And a picture of her hands holding a tape measure along his cock. A full 9 uncut inches.

My wife and I were Christians and she wanted to "save herself" for marriage.
After the wedding she found out that I have a very tiny penis, but she had nothing to compare it to so she went unsatisfied and frustrated. Then she talked to some of her friends and she realized what she was missing. She became angry and dominant telling me that I wasn't "man enough" for her. She became very friendly with a handsome young bachelor in our church and invited him on a date. They hit it off and so I have been left home a lot while she and he continue their affair. I have found satisfaction by wearing girly lingerie and looking at porn. She told me to move into the back bedroom because her lover was going to live with us. He's a very nice young man, but my wife has him walk around the house nude and she often point out that his penis is bigger than mine. Sometime she flirts with him in front of me and he gets an erection. Then she tells me to put on my lingerie so she can humiliate me in front of him. Last week she got a ruler, measured my hard penis at 3" and his at 7". She and he are very happy together and I have learned to enjoy playing with myself and watching porn.

My wife moved me into the back bedroom after taking a lover with a cock twice my size. She would go to him a couple of times a week and always showed me that even after half hour getting home her pussy would still be gaping open. She could nearly feel my cock anymore and I’m about 5inches but quite thick. After a year and me constantly asking if I could at least watch she refused because I knew him. One night she came home and said I can’t live without him and I need his cock every day so you got two options leave or move into back bedroom because I’m moving him in at the weekend. I got home at 6pm and could hear the fucking come and see who’s fucking my brains out. Imagine my surprise when I saw that it was her brother

My girlfriend once asked me what does "beating your meat "mean?? I told her it just means jacking off. She then asked me if I "jack off" and I told her "yes". So she asked me to show her how It's done. So I took my dick out and jacked off in front of her until I came. She was so turned on, we had wild sex right after that.

To tell someone

Just get out the tape measure and let her go for it length and thickness while flacid, length and thickness while on horn

Could be her girfriend(s) asked. Or could be she's comparing your dick to someone else's. Ask her. Now
