A young man, is a man from 20- 25 years old, certainly not a boy in his teens...even a 16 year old is NOT a young man....sorry!
In Germany, where Milo grew up, age of consent is 14. Europeans are much more sexually open than Americans. I'm not making an argument that it's right or wrong, just stating facts.
And I hate to break this to you but when I turned 18 in 1977, virtually no one I knew my age was a virgin who had no sexual experience. I can only imagine what it's like today. So if you want to live in a bubble where young people don't have sexual experiences before age 18, that's your hang up and no one else's. I lost my virginity at age 15 and believe me, I was trying long before that.
Being open and honest about these things doesn't mean we condone or approve of it.
