Of course, from a psychological point of view, this is an alternative behavior. Why do you say that? Psychology believes that when a person's desire cannot be directly realized, biological experience instinctively satisfies the current desire through other ways. To put it bluntly, when kissing, the stimulation of the lips will lead to physical reflection and sexual desire.

He satisfies his own needs through touch, so that his inner desires can be vented and his psychology can be naturally satisfied, and he will feel very happy.
