I have read various stories from guys who say they often fantasize about eating their own cum, but after they orgasm, they completely lose the desire to swallow it. I can fully relate, as I have experienced this as well. Often, as I am stroking myself, I get very aroused thinking about eating my cum, especially if I am reading a story about either a guy or girl eating cum as well. I really love stories about a guy coming in a girl's mouth, and her feeding his come back to him while kissing, or someone licking their come off their partners body. However, when I do actually orgasm, I just lose the strong desire to eat my cum that I had.
On a few occasions however, I have had something happen that enabled me to fully live out this fantasy. The first time it happened, I hadn't had the opportunity to masturbate for a few days, making me extremely horny. When I was finally able to, I wanted to make my self pleasure session last, so I was holding off my orgasm as long as I could. I would work myself up to the brink, then stop stroking and calm down a bit before continuing. After doing this several times, when I stopped stroking, and started calming down, my cock suddenly began oozing a steady stream of semen. There was no feeling of orgasm or ejaculation, just a large amount of cum steadily dribbled out of my cock. As I was still extremely aroused and turned on at the thought of eating it, I scooped it up and began licking it out of my hand. In my extremely horny state, it tasted wonderful, and I licked up every drop I could get. After I finished all of my cum, I resumed stroking my very hard cock, until I actually reached orgasm. I then managed to ejaculate a smaller load, but once again, I lost the desire to swallow it. I have experienced this same phenomena a few times with the same effect. It would be great if I could train myself to do this on a regular basis.
