accidentally saw my father's Penis ?!?!

so i was at the beach with the family and we were having a normal day when my dad wants to go swim so I said "of course" and went with him.

while we were in the water , we were throwing around a pool noodle

he threw the noodle and it landed on the water. when i looked down, i saw a different noodle instead.

it wasn't pleasant and i probably would not do it again. he hasn't talked to me since. idk why his dick was out.

he hasn't invited to the beach again.

how can i make this right ?!?!?!?
