I like to be able to hold them up with one arm during sex. You can do certain moves that just aren't possible with taller or bigger girls. I think it's hilarious my friend's wife needed a crate to stand on at the wedding because she was like 5'0 and he is 6'10
I'm 6'1" (maybe that's not Jack and the Beanstalk tall, but I think it's tall enough). I can definitely tell you that I have a thing for the taller natural "model type" of girls, although personality and character is what's most important to me. And who says you can't be tall and cute?
Usually not actually a big deal for me, tbh I often prefer girls either the same height or just shorter than me, but shorter girls, the thing is the height matches up better if you're shagging standing up
