tl;dr: Give people a mask and they will show their true selves. (credit to YouTube account Eni[X] )

Explanation: Girls will always deny that they have had sex on the first date. It's so obvious that almost all of them are lying from their initial responses. Bet you the ones that don't show it through their facial expressions have really good poker faces and are probably the more intelligent ones of the group. Of course a woman doesn't want to have it on camera that she would have sex on a first date - that would make her look like a "whore" to other girls and be a social outcast. However, when they're asked about their FRIENDS - well, you can see the video for yourself. The woman don't struggle at all to tell the cameraman their anonymous friend's escapades though. The interesting part is, they seem to express guilt at lying about the previous question by their facial expressions as well. Watch them closely and it's all too obvious - women will sleep with a man they find attractive and sexually appealing very early on - probably 90% of them within two dates !

Lessons learned: Go for sex early on. She wants it. You want it. Don't be afraid to go for what you want. There is a reason she is going on a date with you - she's sexually attracted to you. You both want to fuck!
