I have masturbated an average of once a day since I was 12. This adds up to over 13000 times. Needless to say, I have tried countless techniques and methods and I still enjoy reading here and trying other things.
One of my favorite things to do is taste my own precum and semen. When I was younger and more nimble, I would lay on the floor then scoot to a wall and push my legs up so that my penis was directly above my face then I would jerk off until I would cum on my face and hopefully shoot some sperm into my open mouth. What I do now is jackoff until I am to the point of orgasm then stop but use my pushing muscles (as if peeing) to force out some semen. Then I just use my fingers to wipe it from my cock head and lick it off. I will also use a little of the semen as a lube and keep stroking. I can do this 2 or 3 times before losing control and having a full orgasm, cumming all over my stomach and chest.
I do have to be in the right mood to do this as it doesn't always turn me on. And once I've fully orgasmed, I seem to lose interest in tasting myself. But if I don't clean my cock head off after cumming and leave some sperm on it, I will later wipe it off and lick my fingers. I'm not sure why I lose interest after orgasm, I assume it's a chemical or hormone thing. I've often thought if I was gay, I would probably love licking and sucking down a partner's sperm. But I have no interest in even trying sex with another man so that's just a theory.
I've also cum into a cup with the intent of drinking it but have only followed through with it once. And I even liked it but I still lose the desire after orgasming. Just a limitation I have, I guess. I often fantasize about doing oral on my girlfriend after cumming inside her but she doesn't have any interest. I guess she thinks it's gross, I don't know, I've not pushed the subject.
So if you haven't tried tasting your own cum, give it a try. It can be a new experience for you. :-)
