With women I prefer long, slow lovemaking sessions, using many positions and (hopefully) producing multiple orgasms on her part. Which positions become my favorites depends a lot on the gal and her own preferences.
Visually, if she has a particularly nice hourglass shape with an ass and legs to die for I like doggie the best. Like others posting on this thread I enjoy seeing my meat sliding in and out but the main visual treat for me is just seeing that beautiful ass and slender waist while pumping away. If it's her breasts that are to die for then visually my favorite would be face to face with her on top so I can see those tits bounce, sway and wiggle while she rides my cock.
Palpably it can vary a bit, depending on how tight she is. I can really get into slamming a loose, sloppy pussy but with the reduced penile sensation it helps a lot to feel my balls slapping flesh. For that there's nothing better than the aforementioned doggy and her on top positions because they leave my balls free to fly wild. With a tight but well lubed pussy (preferably natural lube) the position is far less important as my cock is being so stimulated that the only challenge is to not cum too quickly. Indeed, one of the previous two positions while fucking a tight pussy can actually be too stimulating and foreshorten my endurance. I guess my favorite position for a tight pussy is missionary but, as rtg likes it, with her legs in the air and her ass turned up for deep penetration. I love feeling my balls pressing into her butt cheeks in that position but it is less stimulating than having them slapping flesh.
As for my finally cumming, nothing beats plain old missionary in a passionate, lip-locked embrace. With a relatively tight pussy I can easily reach orgasm that way. With a relatively loose pussy my favorite technique is to have her bring her legs tightly together and I'll straddle them with my own legs while pushing forward and putting pressure on her clit with the top of my hard shaft. That also increases the pressure and sensation on the most sensitive underside of my glans and it doesn't take much of that before I blow.
But in the end (pun intended) it doesn't matter too much ..... it's all good!
