Doggy and variations of it, like 'face down ass up', lol, or standing but bent over at the hips. I like the submissiveness of the position, and while it's great at a mellower pace, it's amazing when it's fast and forceful and dominating. To me anyway. =P Most effective position in my experience for vaginal and anal stimulation at the same time, easy to get hands involved.
Flat on my stomach with legs together and a pillow under my hips, entered from behind. It's a tight fit and hits the g-spot really nicely, as well as those deep spots surrounding the cervix, with a small adjustment in angle. Great for hair-pulling and choking and really feeling submissive. But if you put your weight on your knees and keep them slightly bent for leverage, you can actually thrust back a little bit and match his rhythm.
Missionary, with legs up like around the waist, over the shoulders, or pushed/held back against my chest. The variations help hit a bunch of really nice spots. You get your face to face intimacy, you can kiss and stimulate many areas of the body at the same time, you can thrust back pretty easily. If he sits back on his heels instead of being on top of me, he can watch the action for a good visual, and either he or I have access to clit stimulation during sex. The position can be sweet and intimate, and you can just as easily flip it completely in the opposite direction, ahahs
just read about it that one you mentioned at the begenning of the second paragraph is Jocky
Cowboy position
or mastery position
gonna sound boring, but I actually LOVE missionary. the key is to not do the standard, married-for-20-years missionary, and just lay on top. you gotta get the legs up over the shoulders, and it's best to do something different than each leg on each shoulder. basically, you'd want (for example) her left leg on your left shoulder (which will be opposite since you're facing each other), or BOTH legs on one shoulder. essentially, you're elevating her a few inches because she'll be halfway on her side. that helps me out a lot because I'm tall and have long legs, it's tough to get low. also, if you're hitting it on a couch, or fouton, or a boxspring and mattress that are just on the floor, you can go missionary with the guy kneeling on the floor and the girl on the couch, etc.
i guess I prefer it because I'm a "lights-on" kinda guy, and I like to see the penetration. and I just like the way a beautiful girl looks just laying there. probably my favorite thing in sex is teasing my girl by going slowly and just putting it in a little, then back out, in a little more, back out, a little mo-- ALL OF IT, hahaha. best way I can describe it, haha. but she goes nuts. so particularly with this girl it's beneficial. only thing is, you gotta save that move for later in the game. it feels as good for me as it does for her, and if I pull that out first, it's gonna be short party, hahaha.
Spooning:
Leaves the guy's hands free to roam, and with the bed supporting your weight and minimal movement needed, you can comfortably do this for a LONG time. link
Jockey:
Girls sometimes are unsure about this at first, but it gives really good G-spot stimulation and almost always becomes a favorite. Unfortunately, if she has a bigger butt, it may be difficult or impossible to do. link
Prison Guard
This is great for when you want it nice and hard and the girl wants to feel dominated. You can do the same thing in Doggy position as well: pulling her arms back and using them as leverage to thrust harder/faster. link
Mastery (variants)
You can do this on a bed or couch as pictured, but it also works great in a chair, both the armless dinner-chair type (or even a toilet if your only privacy is a bathroom), or with an armchair. And the girl doesn't have to be the one moving, she can "hover" and let the guy thrust too. It's good for kissing and breast sucking as well. link link
Nice links MrOracle. That Jockey one is what I called Speed Bump. The Mastery one is what I suggested in an overstuffed chair. I think it works best in a chair.

What's Your Opinion? Sign Up Now!doggie style, My man is smaller than my past bf's so he feels just as big as they did when he's hitting it from behind
Doggy feels amazing because he will hit your g spot and get a good slap on your ass. Cowgirl is my next favorite because he can go far inside you. Try with your legs over his shoulders too, that is if your flexible enough for it. Sex is fun no matter what position(:
Woman on top, because I love the visual. I am very attracted to a woman's breasts (although they do not have to be big) and her hair, particularly if it's long. The beauty of the woman is right before my eyes when I'm in this position. I can also look down between our bodies and see the actual penetration occurring. Very erotic.
My second favorite position is doggie style. Again, terrific visuals.
1 & 2 - don't know (virgin)
3 - giving a hj
4 - rubbing, fondling, biting my breasts
5 - bright colors
I'd have to say:
Folded Deck Chair
There are a lot of really great ones, but I think this one, and regular Deck Chair, but with her knees spread wider, are the very best. You get super deep, but you can see her face react to every little thing, plus you get a great view of her whole body too. You just get everything good all at the same time in this position. link
