I think sexual activity very slightly effects some physical development in teens.?

I'm 18 years old and I havn't been able to grow a full beard yet... I know this isn't rare, there are plenty of kids my age with the same issue... But I think I might know a contributing factor... All of my friends my age who have had sex regularly, weather it be with a girl friend or many girls, from about age 16 to now (age 18) can grow a full beard with ease... And then everyone I know who hasn't had much sexual activity (for example, I have only had intercourse a few times) dont have much facial hair... I'm convinced the facial hair growing faster in some guys is atributed to sexual intercourse at an early age, not mutual masterbation or oral intercourse. I think there might be hormones or locked brain activity that might be unlocked by early maturity partly/mostly from sexual intercourse.

Anyway my questions are...

Has anyone else noticed somthing like this as well?
and
Does anyone know of any studies that might cover this topic?

Inside your question there already is the answer you asked.
In fact, young guys already having a complete sexual life - with g/f as you mentioned - means they have a stronger sex-drive (and more testosterone) and thus beard too is involved. Overall, hair - as a secondary sexual characteristic - depends on hormones amount and work!
Hormones regulate and drive development and glands work. There's nothing strange or unknown for that!

Curious thought... but it could be the other way around... early hormonal development leads to early sexual activity and early beard growth...

Did you know that sexual abuse at an even younger age leads to an earlier onset of puberty, and earlier sexual maturity?
