This thread has been a fun read. Based on my considerable experience, eating cum -- your own or another man's -- is one of those things that one is either into in a pretty big way or not at all. Speaking for myself, I have always eaten my own cum after masterbating since I was kid, and I still do as a grown man. I like the sweet salty taste of it, and for me, it's a basic part jerking off. I don't smole, drink heavily, or take a lot of medicines, so (I guess that's why) my cum is among some the best tasting I have ever had.
I love watching porn videos where guys eat their own jizz, too.
Watching another man lap up my cum is the hottest things for me, and I like eating his, as well. Within safe sex parameters, it's not something I get to do often enough, unfortnately, as you really need to be sure of one another's health status. Still, whether done in love or lust, having your cum eaten or eating someone else's is such a hot and intimate experience between two men. You feel so recieved.
