Making propositions seen as strange or honest?

Well you can do what one of my coworkers said he tried...

He'd go up to girls and ask "Do you want to have pizza and sex".
If they said "No" he'd ask them why they didn't like pizza.

Results... he claimed he got the following reactions (all about 1/3 of the time for each)

1) Slapped
2) The girl laughed and at least talked to him
3) Laid

he said a 1/3 chance of getting laid wasn't bad.

That's way too upfront.
Most women actually want to get to know the person first.
If you want a quick fuck, get a prostitute.

If women had anywhere near the sex drive that men do, your approach would be standard procedure.

I think I heard from someone that you'd probably get a hit rate of about 1 in 10 in a bar. The rest would probably slap you :/ Any where else you'd be lucky to get any at all.

It might not work because girls like to flirt alot.. or atleast some do.

Women don't want to be asked for sex, they want to be tricked and deceived into it by any means necessary. Tell them they're not fat or they're prettier than their friends, that sort of thing. You have to at least feign some sort of interest in their personality to a sufficient degree so that they don't completely hate themselves for having sex with a man

Have a friend get it on video camera. That would make for some classic footage to watch for later.

If I got approached by a very sexy man who asked me this, I would certainly go for it.

I think that you can develop a sense of people's stance. Bars are a difficult place to read people. Much easier to catch onto the projections of a girl at a smaller party or friends of friends setting...or even at work. And I definitely wouldn't state "do you wanna fuck.." ..that's too forward. If anything, state that you've been working so much (or whatever) that you haven't had time to do anything fun.

some girls would like that but not enough to warrant saying it to everyone :)

I would imagine it depends on what kind of bar you go to, and what kind of woman you ask. Also, are you in Nevada? Another important factor. Most women, including myself, would call you a creep and walk away. Some would slap you, a rare few would grab your hand and walk you to the nearest bathroom and some would probably say something along the lines of "That will be $100"

In summation, it entirely depends on the circumstances.

Reminds me of this great scene in "A Beautiful Mind":

I saw on Youtube where a guy made 200 approaches to ask straight out for sex and got rejected 199 times. But the one that agreed was pretty hot!

While such an approach seems uncivilized or vulgar to me, the biggest PUA I even knew would sometimes drive down this large Avenue in a large city near me late at night, and when he spied a couple of women in a car, he would roll his window down and say "Wanna f*ck?" He got laid ALL the time.

There should be a "it just seems like a bad idea" option.

Totally normal, I want a confident gal that know what she wants, I have but had to pay ^_^

Believe it or not it sometimes works with the really cute innocent types...don't be scary but just describe what you would love to do to them..the problem is these girls always have a friend that will try to cock block you...

The thing is, if I was there for the same reason, or open to it and the guy asking, who is honest, so there's a good trait and if he's got swagger/charisma and a dick exceeding 7inches, we may have liftoff shuttle to base!

Famous 20th century physicist Richard Feynman talks in his book "Surely your joking, Mr. Feynman" about how he used that very approach (you described) with women in bars to get laid. He said it worked enough of the time that it was well worth it, because the approach saved time and money. In a packed bar of many single women, he could get laid using this technique almost every night he tried. Who are we to shrug this result off? Feynman was probably a lot smarter than us. :)

No, not to most women...If you are an average guy and just want to have sex without beating around the bush, no courtship, no games, flirting, no foreplay, no conversation, no chasing---you pay for a prostitute... and you're both getting something out of it (you're getting laid without much complication, and she's getting paid to keep her mouth shut and not expect anything)...but if you're talking most regular women (not all but most), yeah it doesn't work that way unless you are a baller, millionaire, or famous actor....I am calling it like I see it---these types can simply ask for sex and they'll get it without much work, if they keep the girl around it will eventually require an investment of time and resources....I was under the impression that men are hunters, that they enjoy competition and working hard for something...so wouldn't you get bored if you got laid all the time by just asking without any challenge, work, flirting, or chasing involved? The baller, actor, millionaire will get bored of having a woman around easily providing sex he doesn't have to work to hard to get....even men in relationships and married men get bored with getting it easily and that's why you have so many articles dedicated to advising people on keeping relationships and sex fresh and new (as in the days when you first courted, chased and challenged each other for it)...so yeah, dude, if you want some, put a little effort into it....
