Yeah anal missionary is pretty cool. I personally enjoy doing anal from the back, yes the classic doggy style. I love seeing my cock split my gf's big beautiful buns, and then watching her ass cheeks jiggle as a I pound her anus, it's a work of art. From the front you can see the titties jiggle around, but I'm more of an ass man, I love to see that big butt wiggle as I pound her ass into orgasm.
Much depends on how experienced the partner is to anal sex. For the total Anal Virgin, I have always found the Spoons position best (lying on one's side), as this makes penetration easier - it's also the position that doctors use when performing an anal examination, with good reason. For the more experienced partner, I prefer to use the basic Missionary Pisition, with their legs resting on my shoulders.
