Hi Lilith,
I've read all the posts in the thread, but wasn't sure if you had actually said to him, "You don't give me enough foreplay, and I want you to give other parts of my body attention, such as shoulders, back, neck, inner thighs etc?"
For men, we're all about having that orgasm. I've often felt, that women can enjoy foreplay and kissing for hours and hours on end, but for guys....all we're concerned about is getting off, and it's somethin we have to take a conscious effort to make sure we are doing what our partner wants too.
Maybe you could try and make it a game, whereby he has access to your clit after X amount of minutes of giving you attention on other areas of your body? I know it seems like an immature way of doing it, but if you can incorporate it into some sort of role play, then it could work?
But as other people have said, it looks like you just have to be explicit. One thing that concerned me though, is that you said he "wont" read the information you give to him about what women want sexually. That to me shows a lack of consideration, but maybe he just doesnt realise how important it is to you.
One more thing, if you do explicitly tell him what you want, be very very tactful, because it might make him feel as though he hasn't been satisfying you...and that is never what a man wants to hear!
Also, the clit is almost a comfort zone for some guys, because it's easier to get a positive reaction from peasuring the clit then it is the neck for example. Men love short term rewards and direct results, and you get that from the clit. You get an immediate reaction from sucking the clit, but you don't get as much of a reaction from gently running your fingers down your partners body for example, so maybe encouragement and guidance as to what you like might help him....and also really let him know you enjoy what he's doing when he engages in foreplay.
You mention your a screamer....i'm guessing that's gna be when ur having ur orgasm...so ur guy might associate screming to pleasure...and your pleasure to your clit? Try and explain how much more pleasure you'll get if the whole experience is prolonged and if your whole body feels it rather than just your clit.
Sorry for the essay and good luck!
P.S. - Sorry to all the blokes for the generalisations! lol
