So, can vegans swallow? Semen is an animal product, because men are animals and, as we know, being vegan strictly prohibits consuming or using anything that is an animal product. Plus, what if your partner isn’t a vegan? If you are what you eat, would you indirectly be consuming meat or dairy?
Semen contains sperm, which are alive. So, not only are you consuming something that came from a living thing, but you’re also technically consuming an actual living thing – a lot of them, in fact.

Well OP doesn't vegan or not.
