A person's height doesn't matter when they're on their backs. (if you know what i mean)

WRONG!

I'm about 6'4", and my wife is 5'4" - trust me, it can certainly matter given the position you choose, otherwise I wouldn't seriously be considering getting one of those sex cushions or swings...


Birdgirl is correct in regards to her evolutionary musings as well...
I'm not sure how I'd feel with a mate the same height or taller than me, just because I've never tried it. All of the ladies I've had the pleasure of being with have all been drastically shorter than I, it just worked out that way - I don't have a petite chick fetish, honest!
