Many women wonder what men want in bed. They have very little to worry about.
Generally speaking men are too concerned with their "performance" to be wanting something in particular from their partner.
The average man is wondering if he is large enough, firm enough, able to last long enough etc.
On the other hand, he is happy he has got this far. This all makes for a good situation for the woman. If you are wondering what men want in bed, they want to know they are doing a good job in satisfying the woman. So women, you can relax about this. If anything, just express your feelings and the man will feel he is a pretty good lover.
