There was a good description what women want in bed described by Marni Kinrys on you tube.
Quited below is what she says women secretely crave in the bedroom:
6 Things Women Secretly Crave In The Bedroom (BUT Are Afraid To Say) by Marni Kinrys
1) foreplay: do not rush, build anticipation, time is needed, take it slow (touching all over, dirty talk, kissing)
2) Commands: women like decisive leadership, say what you want, say with conviction like you know what you want (ie, turn over, spread your legs, get on this pillow)
3) physical Dominance: not just pound hard, but how you handle her body in the journey—a little rough (spank, hair pull, move her around and pick up, pin down with consent
4) appreciation: communicate that you like it, how good it feels inside of her, how strongly they turn you on, appreciate her body and lust, moan and grunt
5)oral and finger action: do it, and get good at it. 80% of women cannot cum without this
6) Presence: be mentally with them, and fully mind meld. Sex is an intimate emotional connection. If fully attentive, you can notice her feedback, so you know what she likes and does not (through her breathing, etc)
the above is from the you tube site by Marni Kinrys.
