I don't mind any positions, but I prefer positions where you can be more embraced and have eye-contact for myself, like having the guy sitting up when you're on top, because I mostly enjoy sex for the connection and emotions that comes with it. But I can also enjoy the type of sex where you're basically used as an anonymous piece of meat, but ONLY with the right kind of guy. i.e. really strong, sexual, dominant, and GREAT in bed, and that I really love him and like to be submissive to him. That can be really hot.
Otherwise I can't be turned on like that and I just want sex for the closeness. I guess this can be the case for some women that they feel that way all the time. Don't think the problem is so much they feel degraded, more that it makes them feel unloved, as when a guy is in a loving state of mind and want to explore it he'll go about it in a different way. While if it's just pure lust you might as well be a random piece of meat, so that can be a bit of a slap in the face. I've heard many girls complain about their sexual experiences and how it made them feel like shit and just made them feel more alone, etc.
I guess this can be hard for men to understand as they rarely run into this problem. They can set the terms to suit their mood and don't often end up in the position where they have to beg for being handled more lovingly, or either way is fine by them, as men aren't as vulnerable that way. Their concerns are mostly if they'll get to do all the dirty things they fantasise about, but this isn't such a sensitive issue that will lead them to feel unloved or rejected, etc. So yea, I think this is one of the main problems in the sexual conflict between men and women, and a reason it's so hard for guys to get laid. I mean, if as a woman you felt you could count on having a great sexual experience most of the time you might be a bit more generous, to put it that way. If men want to get laid they also need to think about how to make it a good experience for the woman and not just about how they can grab as much as possible for themselves.
Anyway, it's not really positions that make up sexuality. Everyone are sexually different and sex can be experienced on several different levels. At the base of it, the purely physical level, like the need to eat. The emotional level, or feelings of passion, excitment, exhileration, or mild feelings of affection and closeness. And at the highest level, or the spiritual level, which is experienced as pure bliss and ecstacy when you reach that level of love and oneness with another human being (totally un-physical, comparable to the greatest drug-high).
So everyone are different and that is fine by me. Personally, I don't get much out of the physical experience alone. I mostly enjoy it emotionally and spiritually, which I find myself fortunate for, as it's so much more rewarding. And at least I have a way of getting high naturally. When I said giving oralsex is better than Ecstacy, I meant it literally, or at least it can be with the right person. The problem is finding that person who can make me feel that way. And he also has to have access to some of those feelings, obviously.
