Virginity

So I'm a 17 year old straigh girl, and I have 0 esperience in sex, love, relationship and in dating. But I question it. The thing that I want to know the most is when is the time to lose your virginity. I know that 'it's when you feel okay with it'' but I want a more especific thing, I want to know from where it is fine and 'okay' to lose it. When I was 10 and watch a movie where the couple had sex and they where 17 I thought like ''wow they are teens so I guess is fine'' but now that I'm 17 I always get chocked when I see people in my age that have already had sex. I don't feel that it's wrong, you do you boo, but I just don't know if this feeling of ''it's not the time so stop'' is somehow okay or am I wrong and having sex in my age is COMPLETLY normal. Tell me your experience pleaseeee
