How I found out about her ex's size

A few years ago my girlfriend at the time and some friends and I were in a discord call and the topic of sex positions came up. They asked her what her favorite position was and I called out for her saying "Cow girl!" because she had told me she wanted to try it. I realize this was a stupid thing to do but there was a lot of drinking going on. Embarrassingly, she said "uhh actually it's the Amazon Position"

Everyone else was intrigued but I was just confused. I had been with her almost two years at this point and she didnt mention Amazon once. I responded "I'm surprised you havent suggested we try it." and she sheepishly responded "well we cant really.. I dont think it would work with us" which got a good chuckle from the group. I realized that this is not something to discuss with an audience to I let someone else change the subject.

We talked about it later and she said that it was her favorite position to try with her ex husband, but that we aren't physically compatible to do that position like they used to be. What I thought at the time what she was referring to was her weight. She had put on about 50-70 lbs since her divorce. I thought she was beautiful at any weight but I could see how a position where she has to balance her weight on me could be an issue. So I made a reddit post asking for advice on how to make it work with a bigger girl. Much to my dismay, the top comment was about how the weight likely wasnt the issue, but rather my smaller dick. I decided to ask her if this was true and she said it absolutely was.

"I didnt want to say it because I didnt want to hurt your feelings. But since you asked I dont want to lie to you, your penis is a little too small for Amazon and that's okay." She reaffirmed that she wasnt unhappy with our sex life but said "we were able to do a lot of positions like the Bow position, doggy style, and Amazon that i cant do with you." I kept insisting we could make it work. Eventually she broke down and said "I appreciate you putting in the effort but at the end of the day, it's just easier to be creative sexually when you have an extra three inches to work with". I've had a four incher my whole adult life so it wasnt a shock to me to hear it was small. But 3" is a huge gap to try to make up

I had assumed she was talking about him wearing a penis sleeve, since we had discussions about me wearing one for her. I said "if he could make it work with the sleeve than maybe I could too". and finally she said "he never wore a sleeve, he was just seven and a half inches long." That hit like a punch in the gut. I hoped that it wasnt true, because maybe she didnt actually measure and was just approximating, but she wasnt angry at me or trying to hurt me, so I dont think she was intentionally exaggerating. But for the rest of that relationship, I wasnt able to get the vision of his dick fucking her out of my mind. We ended up not trying Amazon. We had tried doggy style a few times but I've always had a hard time reaching her pussy. i wanted to keep trying but she was quick to say, "forget it lets just do missionary/cowgirl" which I'm proud to say my four incher could make her cum in missionary so ge's not without value o7
