I believe there have been several threads about this topic. I assume that the question comes up because someone is either curious and has never done it or does do it and is seeking "affirmation" about it from others.
If you've never tasted your own cum, I suggest that you ejaculate onto a bit of food - a cookie, a bowl of berries, a piece of chocolate. That might make it easier to get over any "yuck" factor. Once you've done that, you might become more comfortable just going straight-up with eating your own.
Personally, I've recently cum into a glass and just picked it up and swallowed. I also frequently cum onto a tablespoon and eat it from there.
