If I had given oral to a guy and he came in my mouth, then the next day after brushing my teeth twice and eating and drinking, is there still any left in there? If he put a finger in could be transferred from there into the vagina?

Just like if you drink some orange juice, it is not going to be in your mouth days -- or even hours -- later, the same is true for seminal fluid.

Sounds like you could use a primer on how human reproduction does (and doesn't) work. We have one right here: http://www.scarleteen.com/article/bodie ... production
