If partner is male, consider being on the receiving end of some anal sex. If that is not to taste, try doggy style. If orgasm is indeed the desired end result, standing up might keep him far from orgasm, and receiving anal sex tends to keep her furthest from orgasm. What might feel great for her might be uncomfortable for him. Or vice versa.
Some positions are slightly touchy and require a very high level of turn-on.
Of course men and women differ in what is physically comfortable or uncomfortable. For men, the most comfortable position is receiving oral, followed by woman on top, and then doggy style. The least most comfortable position is standing. Receiving anal sex and standing were voted the least comfortable. Standing and anal sex tends to be a little awkward, even potentially painful, and thus should be attempted with delicacy and awareness.
