Once more, you and I are talking about completely different things. You're talking about using conversation as a means of selecting what you want from a menu.
I'm talking about a partner who can read your body during sex and know intuitively when to touch a certain spot, to speed up or slow down, squeeze harder or change angles...or know that you've had enough of one thing and are ripe for the next.
Ah, I see! Sorry, after the 1,000th person on LPSG has said that talking about sex ruins it so one should just hint and guess and try to read the other person instead that I jumped to the conclusion that's what you're talking about, too!
I do love it when lovers are really great at reading body language and signals and I've been lucky to have a few who can and are really excellent at it. It is a wonderful skill to find in a man and the men who possess the ability to do that do make great lovers!
TheBoyfriend is like most men, though, and he isn't the best at reading women. In my experience, most men are terrible at it! In that "noise" thread so many men talked about sleeping with women who did not react during sex, make noise, or move, and simply announced "I came!" when they were finished which they would have never noticed if they weren't told. It's possible that those women gave no indication, or like you and cbrmale both implied, that those men couldn't read the women that they were sleeping with. With those men, you do have to resort to verbalizing what you like and don't like, what works and what doesn't, which I don't mind doing, if they don't mind it, either. Actually, if he can't read me and it bothers him if I tried to tell him, then I'd stop seeing him.
That doesn't work like a script either, though, saying what feels good if he can't just read you. Just saying, "Oooh! That feels great!" while he's licking, or, "I like it when you occasionally take a lap around my labia when you're licking me, but not when I'm about to orgasm. My labia are very sensitive, but I prefer more focus on my clit close to orgasm. I also enjoy ice cream licks from the bottom all the way to the top with your tongue flat. That's a great way to begin or mix things up every once in a while. Also, I love it when you touch my thighs and my pelvis and my breasts with your hands while you lick. It drives me wild!" It's best to say things like that some other time when his face isn't between your legs because that much detail is hard to do with his tongue on your clit, and it's a little weird to me to be that detailed during actual sex. Then he knows what feels great. If he could read those things about you without you having to say the words, the end result is the same, spoken or unspoken. Both result in him knowing what you like. Neither involves "scripting" sex.
TheBoyfriend can tell when I'm not into something he's doing and that he needs to change to doing something else, and he can read when I'm nearing orgasm and when he needs to continue , but he's not the best at reading me. It really doesn't adversely affect our sexual relationship because I'm often verbal and sort of obvious anyway, with the exclamations of, "Don't stop!" or, "Slow down!" and, "Oh my god that's great!"
