In my limited and cack-handed experience they all vary anatomically and there is no "one size fits all approach". Also, they have different "likes" and sensitivities, indeed the same woman might react differently to same stimulus if it's her time of month. I therefore reckon learning physiology from a book is pointless in terms of punting. I concentrate on enjoying myself and I don't aspire to pleasuring her or making her cum or passing myself off as some sort of sexpert stud.
I'd like to say I'd be more caring and sharing in long-term civvie sex but I'd most probably still just roll on and roll off...........
