It's a matter of preference, I don't think there is any right answer.
I've always been size queen, so I may come up as superficial... As much as I recognize the importance of aesthetic, girth just have an incredible effect on me, its very hard to explain.
As for bedroom play, even though my partner is really blessed in that department we sometime have to supplement with large toys because I really need to feel filled up to orgasm from backdoor play alone.
Of course I'd prefer liking them all equally, I don't know what I'll do if I ever get dumped. The 1% isn't that easy to find. That's just how I am and I have to deal with it...
