I believe the idea about the right time to have sex is subjective. There is no specified time that's perfect except when it comes to our faith. By moral- when we are married. Scientifically- when our body start producing the sex hormones. So it's left for individual to chose when it's the perfect time, but atleast when they're above the age 18.

Exactly, and I know all scientific fact does not apply to everyone all the time so it's person-to-person based. But then there are certain facts that are common and applicable for all. Thank you!
You're welcome.
