When I was in my mid 20s, I got back together with an ex, and after we had sex for the first time since we’d split, she said “oh I’ve missed that”. So I asked her what she meant and she replied “you do know you have a large penis, right?” I didn’t really think much about my penis size at the time, just thought it was normal and average. Anyway, she found a ruler and measured it to try and convince me and prove herself correct. Was very happy to learn I was 7.5 inches. I suspect she told at least one of her girlfriends because much later, long after we’d separated for the final time I had an encounter with one of her friends, who, when seeing/feeling my penis for the first time said “so she wasn’t lying”.
