When building a woman's loyalty sexual game is extremely powerful. This is the two-step process I use.
1. Give her strong, plentiful orgasms, and blow her mind sexually. This is not hard, unless you have a micropenis. A little research and practice goes a long way. Your stroke game, stamina, pussy-eating skills, and pussy massaging techniques have got to be on point. I always quote the Pretty Toney line from
The Mack, "Once I get a bitch, I got a bitch."
2. Once you've hit it a couple of good times, back off. Don't be thirsty. Let her come onto you for sex. You may even want to practice "dick rationing". See this video for the details of that concept.
Keep giving it to her good, though. Try to outdo yourself every time. I am the object of sexual desire with women I deal with. I'm not a strikingly good-looking guy either. I remember Patrice O'Neal saying the same thing on one of the Black Phillip episodes. His girl was beautiful, but he was the sexual object of desire in the relationship.
As far as deep conversation game, I excel at this, because I am naturally a deep conversationalist. I do believe this can build loyalty, especially if you get her to subscribe to your ideologies. This is not hard to
do, either.
