Am I the only one that Haven't fallen in love?

im currently 19 and I haven't fallen in love with someone not even a crush and I feel weird because I feel like im the only like this family and friends always ask me why I dont have any bf and when I told them im not interested on those they always look at me weirdly and I feel a little Hurt sometimes I just can't force myself to like someone romantically

I though oh maybe im just a lesbian and I actually like girls and not guys but I always see pretty girl and still nothing even handsome guys still not feeling anything
