Actually, doggy style is better than on top for a girl. Either that or being on bottom with her legs up on his shoulders, or knees to chest. In positions like this, the vagina lengthens, which means more friction, for both of you. I personally like doggy style, but it's a tad bit tiresome, and isn't as close((I love as much physical touch as possible)), so I like the second option more, even though you have to be careful not to like, mess up her legs.
I think you're only "feeling it more" because you're actually doing the work. You have to focus on it more than you do if you just lay there.
What's really fun is girl handcuffed to bed with legs both SPREAD AND LIFTED tied to the bed posts. Granted, she looks a little funny like that, but she's totally at your will and can't do anything about it without hurting herself in the process.
I find on top to feel better because I can flex around more. Doggystyle, you're just sort of stuck in the same position but on top you can move around, arch your back, lean back, do a few different movements that feel really good.
Handcuffs are awesome. Being a victim is the best ever.
