I KNOW ITS FROM SEX BUT HOW
Sharing bodily fluids with an infected person. Their fluids mix with yours and the std attaches to your cells and there ya go. It doesn’t have to be sex. If you share a needle with an infected person it’s very possible you will become infected too.
If you can’t figure this out…lol DON’T!!! BREED!!!:P
A bacteria or virus is transferred to another person.
