I notice I have to be in the right mood for eating my own cum. On the occasions when I super aroused, I truly enjoy taking in every drop I can....I find it best when I'm edging. When I reach that heightened state where I've edged just a bit over the top, and there's some cum flowing up, but I'm still riding that edge, I haven't yet fully come with a full-on, complete ejaculation... that's when I can really enjoy the taste and texture and simply enjoy the sensation.
I have also enjoyed licking semen from my girlfriend's vagina, both my own and another man's. It's incredible -- and a wonderful experience to share.
