Sex before marriage

I'm a Christian... As of right now I haven't had sex and don't plan to until I'm married. But, times have changed that's undeniable. Is saving myself something that should be of the past? I only ask this because I'm just waiting for the day when I have a boyfriend that I'm totally in love with, but will eventually leave because I won't have sex and he could go find another girl to have sex with. My two really close friends agree with me on saving ourselves for marriage, but it doesn't seem like there's any guys that feel that way anymore. I'm just so scared that I'll never get married, I'll never find true love, I'll never have a family, because guys won't wait. What do you think? 😔
