Back to OP, I with my gf have had similar conversations about her exes (we didn't venture into adding it to our sex life/foreplay tho).
So yeah, she told me about having been with one guy that basically had a "monster" dick and that it left her sore for days. A little shot to my ego due to some clearly off basis beliefs that I want to be the biggest a girl has been with. Other than that, she has always felt uncomfortable about telling me the size of her past partners and what not, telling me that I'm very big and that I have nothing to worry about. I know that I'm pretty high on the size list cuz I know she loves to brag about me and all that. Things anal were even out of the question, even tho she had had it before comfortably and with no pain and was able to take a pretty good intensity with smaller tools. (No we still can't have anal sex comfortably cuz of my size haha)
All that to say that I was curious, and still am a little bit at times but there's no real worries about it. I have been with girls for which I've ended up being the biggest they've been with but size is never something that matters to them in the long run.
