Had protected sex he ejaculated took condom off then i licked his nut off and put it in me what are chances of pregnancy?

Possible: if some of his semen ended up where you licked and it wasn't already dry it is possible you transfered some sperm into your vagina. Not a good idea to do this. You might want to get plan B or another form of emergency birth control to be safe.

Risk: If you licked his scrotum and not his penis, then there could still be ejaculate on the penis. If this were the situation, then pregnancy would be possible.
