There is only a tiny amount of sperm in semen. I think you wanted to ask "it is safe to swallow semen?". Of course it is safe. People have been doing that forever, and I think it is safe to say it never hurt anyone.
its not like your wee has chemicals or anything its just the fluids you've drunk and some safe kinds of acids doh that's a chemical but not harmful it like how people don't find it gross to stand in cow crap because all they eat is grass its not like theyae anything gross.
A tooth is not toxic in itself, but a tooth sometimes has had cavities filled with a substance called amalgam, which contains mercury and is therefore not safe to swallow. So, it depends on the tooth. Some are safe to swallow, some are not.
It's probably not safe to swallow H+ sperm whether you're pregnant or not. I am not a clinical doctor, but this is a question you should ask him or her for a definitive answer to. (And trust me, you won't be the first person to tell her doctor that she swallows semen...)
No the amazon can't always be safe. E.g. There is a type of parrasite that lives in the amazon river called a Candiru that attacks when having sensed urine in the water and they attack the human or thing that released that urine
Swallow, swallow, and keep swallowing without taking a breath. It is not really safe to chug a liquid because you can choke. You will get enough just by drinking regularly and breathing in between swallows.
You should not use baking soda to brush your dog's teeth. Humans may use baking soda because we know not to swallow it, but dogs will inevitably swallow some amount of it and may swallow more than is safe.
There is very little actual chemical physical difference between dog sperm and human sperm soy yes it is perfectly safe to swallow. However the legal ramifications if you are caught doing this would in some country's put you in deep trouble if not in deadly danger.
