Totally depends what you’re seeking. Cowgirl is great b/c it allows me to see & touch all her parts. It also allows her to control the pace and clitoral stimulation is easy in this position, so I find that this is usually the easiest position for a woman to cum in. And it easily moves into many other variations/positions, which is nice. (hovering butterfly is a personal fave).
Any variation of bent over/doggie-style is good for an ol’ fashioned pounding, but is lacking in intimacy and is not too conducive to “making love,” in my opinion. And when I’m making love, I really don’t like to “pull out”—I like to stay in the whole time, which you obviously cannot easily do when moving to/from doggie style. (I have, however, developed the ability/move that allows me to stay in when transitioning to/from missionary/cowgirl, and, if you go slow, you can keep it in when transitioning from cowgirl to doggie-style, so theoretically you can move seemlessly from missionary to doggie, it just takes a little time & effort. You can also move from missionary to doggie by having her put one leg in the air and slowly swing it over your head, slowly moving onto all fours, but this takes time and coordinated movement by both parties).
There is definitely something to be said for the missionary position. In my opinion it is easily the most intimate and allows for easy kissing, which I enjoy (girl on top, laying down on me is also good for this). It also easily moves into other positions, some of which are perennial favorites of mine (ie, holding her legs in the air by her ankles, her legs over my shoulders, her knees next to her ears, etc, etc.) I also really enjoy wrapping my arms completely around her and holding her tight, her wrapping her legs around my waist tightly and slowly grinding away. Quite wonderful, in my book.
Spooning/from behind while lying on our sides is also nice. Her sitting on the kitchen counter while I stand in front of her is also nice. Standing, against the wall or in the shower is also nice. I’m also able to simply hold her in the air while I’m in a slight squat position, which is also rather pleasant. And if we include 69 as a “sexual position,” then it is also one of my faves (so much going on at once—almost a sensory overload!!)
Man, they’re all wonderful!!!
