Help!

I live alone with hubby but due to the Covid, school is not in session so his nephew is here with us for 3 months now. I noticed the boy always stares at my breast and I feel very uncomfortable because it's not occasionally but almost everyday since I'm home now. He's 14. Should I discuss with husband or I should talk to him myself?

####I dress decently but most times I don't wear bra just to feel free.

Thanks will be waiting for responses.
