Silly question but when did you feel your first kicks with a boy?

I’m currently 19 weeks, and I’ve felt more constant flutters/kicks lately from my baby boy, he sits very low. I feel the kicks more when I’m sitting up, while leaning forward.

I’m trying to see will it be any different if I lay down? I never feel him if I am laying down. Also when did you start seeing kicks on the outside?
