Food intake has the most directly influence on taste ...
Ok, I've wondered about this for a long time. What makes (male) cum a certain consistency, texture, etc? Is it what you eat, or how much water you drink? Are there other factors?
Although period between ejaculations has great effect on consistency, thickness, amount, etc..., recent food intake has the most effect on taste.
For me, it affects whether or not I swallow it. Sounds silly, but I hate eggs, and when cum is the consistency of the white part of the egg, I want to throw up, because the texture and the way it feels in my mouth remind me of eggs.
Consistency can have a lot to do with food intake, especially the amount of water (thinner) or amount of sugar (sticky).
Even with a certain guy, it varies. With my fiance sometimes it's really thick and sticky, but other times it's more watery and thin.
While thickness is typically related to period between orgasms as well as more recent water intake, stickiness is clearly related to sugar intake. Stickiness typically means sugar, and it tastes better, although it all depends.
I've also noticed color variations between males...some is more white than others.
Remember, the amount of water intake affects the color anyone's urine. The more water, the less yellow the urine. The less water, the more yellow the urine.
The piping is the same for urine as semen, which is sperm + seminal fluid. So some urine can mix into the seminal fluid, especially if the male has a fuller bladder (the relaxation of the muscles causes some release) or recently used the bathroom (left in the piping) and had very yellowish urine.
Sorry if this is a dumb question, but inquiring minds want to know...
Before engaging in heavy, oral sex, have your partner continue lots of fruits or other sugars, and avoid proteins, especially anything diary-based, at least going back 9-12 hours, if not a full 15-18 hours (I don't have statistics to back this up, but that's been my experience). Fruits with lower acidity, such as minimal or no citrus or citric acid, are most ideal, as they don't add the tart.
Most people, my wife included, prefer Pineapple or Pineapple juice over any other.
