resentment against my mother (please comment)

i am 18 and i know hardly anything about sex. my mother refuses to talk to me about boys, let alone sex. any info i retained was through school, older kids, and the internet. i encourage all mothers to talk to their daughters about sex and what to look out for in a man. my mother told me she would kick the baby out of my back if i got pregnant. and to some degree i believe her. please dont shy away from talking to your children (especially females) about relationships and sex. currently i have been stressing about being pregnant through oral sex and followed by masturbation simply because i know nothing about sex. please be willing to talk about natural feelings and how to deal with them. we could all use the advice. thank you for your time.
