At least for me, knowing that I have a cock that's quite large, I've never asked anything along the lines like "how does mine compare," as that's sort of like begging for compliments. There are men out there that have longer or thicker cocks than mine, but from everything that I have read, they are quite rare. That said, I've had several girlfriends over the years which have brought up the size of my cock in comparison with previous lovers. Just one said that she had been with a guy even longer than I am, though she added that having sex with him was never comfortable. Even if she hadn't added that qualification, it wouldn't have bothered me; I've learned long ago that no matter how smart, handsome, or well endowed you might be, there's always somebody who will be smarter, better looking, or better hung than you somewhere. I'm just grateful for what I have. And should I have been given a much smaller cock, I'm pretty sure that I'd be OK with that as well. While we all do some degree of comparing our current lovers with those who we've had before (it's unavoidable), when I love a woman, it doesn't matter if she's not as shapely, or thin, or pretty as every previous girl I've been with, I just love her for who and what SHE is. I hope that whoever I'm involved with would feel the same about me.
