There are two essential ingredients here - 1) Excellent chemistry; 2) the man has to be confident and assertive, yet tender and firm.
Given those circumstances, a man can take a lady to a beautiful blissful state of endorphin driven, erotic, sensory overload sub space la la land.
If the needed chemistry is not there and/or the guy doesn't know what the hell he's doing, he may just find himself getting bitch slapped! LMAO
