In all three instances, you failed the T-test.
In the first 2 where you have had make outs, the level of testosterone that you have transferred through her saliva was not enough. Note that I said level, not volume. There is no way that you'll dump more saliva in her mouth and increase your testosterone levels. If you want the scientific explanation for this, go to the PUA Lounge and find my How to Make a Woman Fall in Love with You and Other Facts. I've place a link there to the science behind kissing and testosterone.
You can increase your testosterone at the most efficient way through high intensity interval training on cardio and strength. Combined. Make sure that you have no serious medical condition when you do this.
You can also increase your testosterone levels by choosing the right kind of movies, tv shows and music that you get exposed to. Violent movies, action packed tv shows and heart thumping, loud music will help your testosterone levels go high.
Martial arts or any form of activity where you'll engage in competition and aggression is also good for your testosterone levels.
In the third instance, you just didn't escalate enough. Unconsciously, the girl's genetic make up said to her that your testosterone level is not enough-- even without the salivary transfer of your testosterone to her mouth.
