Can a big dick do damage?

My ex boyfriend had a big dick, or so I thought until I saw this one. I ended things with the guy and I have to admit the dick size was a part of why. He was a tall guy, not particularly large but when I saw his dick I couldn't even imagine taking that in. I didn't even want to try so I just listened to my instincts. Of course there was another side to why i ended it which was that I just wanted a more passionate guy and he was too casual for my taste. But this leads me to my question, can a big dick do damage or can we actually stretch? That thing looked like it would tear me.
