By late bloomer, I mean someone who did not have any romantic or sexual experiences while growing up.

Most adolescents will have at least hugged or kissed by the time they're 16, and most start having sex by the time they're 19.

So a late bloomer is someone who has not went out on a date, has not hugged, or kissed or had any of those experiences into their 20s.

Are they developmentally behind? Does this lack of experience stunt them socially? Do they have some catching up to do?

Also, because of their situation, do you think they are less mature when compared to adjust adolescent who has had romantic experiences?
