What’s it like knowing there are big dicks at large?

My gf insists I’m the biggest she’s ever had. I was her 10th guy. Even though I find it hard to believe my ex also claimed I was her biggest. With that being said, What’s it like knowing that you are potentially her smallest and more than that she may have experienced a shlong like mine before you?

It’s very easy to say porn is not real or It’s exaggerated but I’m just a normal guy with a big cock that sleeps with regular pretty women. I don’t live in LA or hang out in celebrity circles. I’m not a “porn star” but I have a porn star cock. I’m otherwise a regular guy you’d pass on the street. And I’m sure there’s a bunch of us out there in your social circles dating the same girls you do. Is that a scary reality or something you’ve already come to terms with?
