My Girl Friend And I Were Messing Around 2 Week,

My Girl friend and I were messing around 2 week, We were completely naked and unprotected, and started to rub our genitals to each other as if we want to do penetration. However, there was no penetration happening at all, and I did not ejaculate anywhere near here afterwards.

Her hymen was still intact (virgin), and as far as I know, I secrete lots of pre-ejaculation fluid during arousal. after mastabation i rub again ..


Is it possible for her to get pregnant ? if so, what is the approximate percentage chance ?

She is currently so stressed that she may be pregnant, please help with some advice :( if pragnent how can prevant
