okay lad listen I have some time to kill so I'm gonna tell you a few things.
Firstly, the sex for a woman is all in her brain. It does not matter that much if you actually have sex for 10 minutes but the build-up is what is important.
Okay, so, considering you are not a complete autist, you can pick up social cues and can see if a girl is interested in you. This should not be hard to do. Be playful, relaxed, confident and smell good. After finding the girl you know almost certainly wants the dick, you switch her around. You go the bar for a drink, you need to get a pizza, you can't find the lighter, it does not matter. You have to get her isolated somehow through a story.
After you get her alone, you talk for a few more minutes/moments and when the silene settles in, you let it go for a bit longer and then you kiss her.
The kiss is very important. This is the make or break moment for her if she will have sex with you or not, more or less. So, the kiss is supposed to be like a flower. Delicate and shy at first and passionate and emotional at the end. A lot of girls or guys only twirl their tongues around which is a huge turn off to anyone that's been kissed more than once.
Do not overthink the kiss. It's better that you go after it and get rejected than to waste an opportunity to fill up that sweet pussy with your man juice.
So, you have to test the waters first with just the lip kissing. The lips touch, they touch again and then you slip her a bit of tongue. A bit. Not the whole thing down her throat. After this, you get in closer, you take her and you hug her a bit/pull her towards you and touch her neck with hand, the other can hold her chin up or just rests on her leg. The kiss should get from the intital shy stage to the fiery I have to have you stage but keep it cool. Keep it cool my man.
After a few minutes of making out, you tell her, You wanna go back to my place? or something along the lines. If she didnt flake on you before, she wont
