I never really give that much thought to the positions that a partner and I adopt during sex. Generally we have a tendency to go with whatever just seems right at the time, and even that is mostly an unconscious choice based on circumstances and what we happen to be doing at that moment. Unless there is some sort of power-play scenario going on where I tell her to “bend over” or “get on her knees”, sex tends to happen in whatever position it happens.
In my younger, more limber, days, I did a lot of experimentation with positions. I wouldn’t go as far as to say I tried the entire kama sutra, but I did discover which ones worked for both me and the woman I was with, which ones were fun (if slightly more trouble than they were worth), and which ones just didn’t do it. After that, as can often happen in longer term relationships, we settled on a small number of positions that were the most enjoyable for us and employed them as was appropriate. That’s not to say I don’t have preferences, but they do tend to be driven by the situation.
For me, one of the most important aspects is the feeling of my partner’s skin against mine. I like positions that give me lots of skin contact. Whether it be her, or me that’s on top doesn’t really matter and will, in any event, probably change during the course of any one “session”; what is important is the feeling of closeness and oneness that comes from intimate skin against skin contact.
Another aspect that I’ve touched on recently is facial expression. Any position where I can watch my partner’s face and see her pleasure in what we are doing reflected in the changes in her expression is going to be high on my list of things that arouse me and intensify my pleasure. As I mentioned in that post, such positions can be face-to-face, or the can involve watching her in a mirror as I fuck her from behind.
Positions that allow me the freedom to also use my hands are also in my go-to file. Whether it be caressing her skin, pulling her hair, squeezing her boobs, spanking her arse as I fuck her, the freedom to be able to add an extra element to what I am doing to/with her, increases the enjoyment for both of us.
A final thing to consider is the “type” of sex that is being had. Some positions such as the straightforward “missionary” lend themselves to comfortable, close, sometimes lazy encounters, e.g. last thing at nigh before falling asleep, or first thing in the morning when you are still not fully awake. Other positions, such as from behind, can lend themselves to harder, rougher, more primal, animalistic couplings. Again, it really just comes down to mood and circumstances and the sort of sex being engaged in.
I guess, what I’m getting at, there are positions for every fuck.
