Me and my girlfriend were having just foreplay, but no intercourse(since she is not ready for that yet). Anyway i wanted to explore more so i used my fingers to pleasure her. Though i did not insert deep in it went in upto 2-3 inches inside. She has not experienced any tear in hymen. Stupidly i had used my hands to rub my penis and i also noticed that significant amount of precum was there. 

 1- Can she get pregnant?

 2-Can precum cause pregnancy?
