So, you're only chance of getting laid off the bat is if you're:

1. Female
2. A celebrity

Damn.

I guess I feel validated being the gentleman I am taking them out for dinner first. It can be done in 3 moves or less but to be safe it's recommended to use 5 moves (e.g. dates first).

Here is how you do it safely:

1. Meet and greet (like at a coffee house just to see if you connect at the basic level)
2. First date (e.g. movie, park, outside event)
3. Second date (at her place or yours, don't try it yet, it shows you respect her in a vulnerable situation, leave at the end of the night)
4. Filler date
5. Sleepover date (this is code for sex, every girl knows what this means and she should feel save by date 5 to do it).

Again, it can be done in less than 3 moves but it's risky and only really works on slutty girls. Five moves is all it takes, I guarantee high success rate.

It's kind of like chess if you think about it. 

Depressing. The funny Thing is even the uglyst Girls say no when in reality they must be happy if some man ask them this question.

This would work better if the line was simply something like

"Hey you look hot tonight. Wanna f*ck?" if you want to be less brash then, "Hey you look hot tonight, wanna get out of here?".

If you're confident about it and you go to a high energy bar/nightclub, festival, or Mardi Gras type environment, and don't really care about rejection, sure you'll probably get laid a couple of times.

The results would´ve probably been a bit different if he was dressing better, wasn´t asking girls who are in a group and if it was a different environment.

Was the girl who accepted pretty?

Or was it the case of you didn´t find her attractive but had sex with her anyway?

Yes, she was the only nice in her group of four friends, although she was a little crazy (something about seeking revenge on her cheating ex-husband by fucking whoever she liked) and she definitely smoked too much. But after all, having a whole beach, and one of the most known in Tuscany, to choose from, it wasn't too difficult to find 50 nice girls to ask, I hadn't to lower my standards.   

maybe if he didn't wear those funny looking socks it would have helped! either way for girls it will be a bit scary since there are chances she will get raped or attacked. not to mention its a bit slutty for girls to say yes to a random stranger asking for sex in a public place like that!!

tbh i was waiting for any of the girls boyfriends to punch him for asking such a rude questions in front of them lol

I read about a similar experiment conducted by a university several years ago.

They picked both a female and a male model, and made them ask people from the other gender on the street for sex. Not a single woman agreed to having sex with the male model, whereas I think about 75% of the asked males agreed to sex with the female model.

This "experiment" didn't prove anything that wasn't already well known. If you send a girl and a guy out and the only thing they're allowed to say is "will you have sex with me?" then it's obvious that the girl is going to get more replies in the affirmative. However, it's pointless because that's not how things happen in reality.
