Started when I was 18, had intense motivation to learn due to a break up, and 2 years later I've got 30 lays under my belt.
What did I do? I went out and approached. I read the GC articles and adopted their core points into my beliefs so I could approach a girl with the confidence to be speak sexually. Although, I'm naturally very socially intuitive so I pick up on alot of signals and body language that isn't so obvious.
Where I went? Where are my stalking grounds? I'm really big on direct day game for more reasons than I have the time to write down right now. But because I preferred direct day game I was mostly on busy streets, local stores, malls. I hate clubs and night game.
How many times I went out? Pretty regularly. More often than not I was out running errands for my family and would purposefully take the routes I knew other people did. So if I needed to go buy milk I wasn't running to the local Mom and Pop shop, I was running towards the grocery store by the mall. Also, what time you go out matters; I stayed away from these places right around 3-4 because that's when high school girls head out. I'm not trying to get charged because a 16 year old looks like a 21 year old.
Easiest method for sex? Ask for it, someone's bound to say yes. Don't literally ask for it but make sure your intentions are clear within the first 5 minutes of approaching her. This is why I'm a fan of the direct approach as well: High risk, high reward but it pays off because you don't waste time with girls who aren't into you, and you know that whatever girls stick around to talk are more than likely down to fuck. Be comfortable talking about your intentions as well because being vague causes girls to auto reject as well because they don't know what you want: a relationship, some pussy, to be friends, etc?
Hope this helped you
