I couldn't agree more.
I've been with a couple of small girls where I was just like, "This is freakin' ridiculous." Why would I want to be with a girl that could only ride me and will not let me ever really get into it b/c of size concerns. I don't expect a girl to accomodate all of my length, but if I'm bottoming her out at the half-way point, or even 2/3 point, the sex is not going to be any good for either of us. It's like one female member posted (sorry I can't remember who), if half of your penis is not penetrating b/c of length, that means that your pelvis is not making contact with her clit. The sex isn't going to be good for her, and I just hate having to concern myself with "taking it easy on her."
