I disagree about missionary being a bad bigdick position.

I think it's actually a really good one for when you are just starting. You get to control the depth, have access to lots of fun pleasure buttons, and can watch the girl's expression. It's only bad if you're planning on going balls deep or if you can't control your thrusts.

I won't stay there (with mish) but it's a nice place to start.

Doggy, Froggy, and Spooning are all nice finishers, though
