Realistically, it’s very similar. You don’t normally exchange it with just anyone for starters. They are both large majority water, converted from your blood’s plasma, containing small amounts of proteins and minerals, and have some mucus. The biggest difference is the digestive enzymes in saliva and the sperm in semen. Obviously they serve different purposes but they are still more alike than they are different.
Saliva has much more bacteria than semen and having semen in your mouth poses zero health concerns besides like STDs but when it’s your own, obviously it doesn’t matter. And with the amount of bacteria we consume on a daily basis, any small amounts found in semen will have no effect on your body.
If you are concerned about having your own bodily fluid in your mouth, why would you be so comfortable with it being in someone else’s? My advice (to all of yall) is wash your penis better and stop being worried about seeming gay or some shit and start worrying more about the woman who is literally giving you oral 🙄
