Having gone out with with literally thousands of women and gone to bed with hundreds over past two and a half decades, I've learned that there's nothing you can do to GUARANTEE having sex with any particular woman.However, by doing a few simple things, you can dramatically INCREASE THE ODDS of going all way on very first night of your relationship.
1. Meet her in a non-traditional venue.
By that I mean, don't take her to a fancy dinner or do anything else that she associates with a "date." If you do, that puts her into same "make him wait" mindset that she adopted with last 100 guys who bought her a nice dinner.
Instead meet her somewhere informal, like a coffee shop or some cheap diner for lunch. Don't make a big deal out of who pays for what, because again, last 100 guys she dated paid for her meal because, as was blatantly obvious to her, they were hoping to get laid.
As an alpha male, you shouldn't do anything because you're "hoping to get laid." That reeks of desperation and kills attraction that a woman feels.
A more attractive guy is one who gets laid all time, so sex is no big deal to him. If a woman wants his attention, she has to earn it. In other words, he is a challenge for her, not a sure thing.
2. Have proper mindset throughout date.
You want to be relaxed and feeling sexual. (To get yourself into a sexual state, try watching porn just before date, but don't masturbate.) And it's important to feel relaxed. No nervousness.
For a woman to become sexual, she needs to feel relaxed and horny. It is important that you feel that exact way yourself, because studies have shown that when two people are in rapport, they eventually match emotional states with each other.
So when you're chilling with girl, you should feel deeply relaxed and horny, and then engage her in conversation about neutral subjects until you see signs that she too is getting relaxed and horny.
3. Get her alone with you.
Let's say you and girl hit it off fantastically in coffee shop, so you then take her to a bar to get a quick drink. Things are really going well there. The conversational vibe is excellent. You see signs of her increasing sexual arousal and openness to intimacy.
