Drink pee is Golden Shower fetish, its one of those kinky one that everyone doesnot like. It cant be health threatening issue unless there is any problem.
Problem means, pee is the liquid extract, comes through kidney stored in bladder. If anyone has diseases like Urinary track Infection, it can be fatal. In general pee is acidic in nature, but doesnot cause much harm like acid. If both of you are okay, go ahead. But its preferred to be vegetarian if you are on to this. In different corners there is a ritual where cow pee are drank. that's because cow is also vegetarian, like xxxxx. There is no food value found, nor anything fatal found on pee.
Drink of ejaculation (semen) is nothing new. a lot of people likes this, a lot doesn't. But this is not kinky as pee. There are some food value on this, you can go for it with your partner. Some people has a smelly one, the rest are okay. Again, its individual choice. I love to take in my mouth but haven't gulped till now, I spit out. Its not a matter of someone has to like, if she doesn't, don't force her. Sex should be enjoyed with consent, not an act someone has to do to please the other.
