I also have a hard time keeping my emotions under control sometimes. I'll tell you the secret.
You need to spin more plates. Have you ever heard the saying "don't put all your eggs in one basket"? This is especially true with woman. Keep a revolving door of pvssy at your disposal always. As soon as one girl starts acting up you just draw your attention way from her and put it towards another. Doing this makes you naturally pass any sh!t test. You show no emotional reaction to anything because in all essence, you really just don't give a damn. The girl you drew your attention from then soon realizes really quickly what is acceptable and what isn't with you. You get her trained like a dog. Before the cycle ends you have them all at your beckoning and your head is always in check.
