Abstinence

What's the best way to tell a guy you've just started dating that you're a virgin and saving yourself for marriage? Without them over reacting and/or changing their mind for the next date... 
     I'be never had a guy react well when I say I'm waiting for marriage because I assume they think I wanna get married tomorrow when I say that ¯_(ツ)_/¯ 
     I'm 19 and living on my own in college
