Hey Y'all, I need some help..

Okay, so I've been with this guy for 9 months. I have known my boyfriend for 6 years and we started dating in May 2017. We've only now have started to like makeout and stuff, Because I'm really shy and my parents are REALLY overprotective. So we never get any alone time. Well I'm only 14. I was talking to my guy friend and he said "Give it a month and y'all will have sex." Which that scared the shit out of me. I know some people would like to have sex before marriage, but I don't want to. I would love to just wait and lose my virginity in a faithful loving marriage. I mean not only will I be doing what I want. I will be keeping my promise to my mom. I just don't know what to do. I don't know if the guy I'm with will stay with me or if he will leave.

Please help me.
