Forums, Medical and Psychology Texts, and so on. The subtleties of dick sucking can be mastered and manipulated quite elegantly through a little academic intention. For example, you could find the hormone patterns that are common to men, to the experience and expectation of blowjobs, and to arousal as a linear versus a n exponential process. This can be applied to social-psychology as a bridge from the biology to that of communication since someone who consumed such research would have a better skill at predicting the situation and imposing a proper facade. There is also learning the techniques, which incorperate handling of foreskin (and what to do with cut dicks), balls, hair, internal components, speed, tension, pressure, breathing control , and the list goes on. There is an entire school of thought and multipe critical views on the process and sociology of oral sex. There’s even stufies on the arousal achieved from attempting to catch and spread STIs. Dick sucking is a classical art that ought to be respected and learned, even by those who would never gape their jaws and spin their tongues.
