Yes, there can be too much of a good thing!
My XBF used to rip me and I'd bleed, in the beginning. I got used to it, but it never was REALLY comfortable. And I've had even bigger...Told one guy he'd just have to put that thing away 'cause it wasn't going in HERE.

The guy I've got now is PERFECT. Big enough so I can feel EVERYTHING and small enough I've got room to breathe!
