It's amazing how each and every person has their own way of pleasuring themselves. Yes, some guys do like the taste of their own cum, and they deliberately masturbate in private just so that they could harvest the seeds that come from his own penis.
From how much pressure he puts in into every stroke, how long he could hold it in before he would finally let it all burst out, and where he decides to release it, either on his hands, on the floor, or in some cases, even on his face and in his mouth. When a person masturbates, he is in total control of everything.
