My son discovered his balls

A few weeks ago I returned from work and my 5 year old son tells me he feels something in his groin area...

I ask him to show me where... Off goes his pants and he starts feeling around and says "here it is"...

I feek where his touching and ask " do you mean this?" And he confirms..

I start bursting out with lafter and tell him "That's your balls son!"

🤣
