Hyähä's Things

I heard a lot that most of Lgbtq+ people are living their first (love, sex) experience in their 20s because of a (lack ?) of relationship with same gender people or because they hadn't define completly their sexuality yet

But most of the Lgbt people I know irl (male, female, nb) are not in this situation At All (no matter their sexuality, bi, pan, gay, lesbian and all)

So I was asking myself, does it's really the case for most of the Lgbt people ?
Or maybe the people I know are just super extrovert or something ?
(btw I'm a 17y/o nb)
