Help I got a pre puberty boy 👦😩😩

Help!! 😩😩 I’m nervous as it’s my oldest.. he’s 11 years old. When do boys become aware of masterbating or how do they learn of it or is it parents telling them? When do they start doing it if they do is he still not probably doing it yet? When can are they old enough to produce cum?? Just curious do they start getting urges and feel balls heavy to cum before 13?

Anyone had a boy and did you talk to him on this matter? How?? Just curious and new to this!!

Thank you I appreciate it!
