i need advice !

i’ve been w my boyfriend for 2 years now. i’m 18 and he’s 19. we haven’t had sex. i want to so bad and he’s just waiting for me to be ready. the reason i won’t do it is because i’m scared that if/when we break up and i’ve had sex, no other man will want me because i’ve had sex.

side note- i live in utah. that’s the culture here i’ve been raised to think this.

is it true though? if i have sex now will i be unwanted by other good guys later on in life?
