Is it wierd for a man to not pleasure himself?

Okay so I keep telling him it’s completely normal to help him self. I just had a baby and he works a lot and if he needs to get one off he’s more them welcome. Well walked on him in the shower and he was super embarrassed and I left him to do his thing. he came into the room and said he doesn’t think it’s normal for a man to play with himself and he was embarrassed that I saw him. Like this man shits in Front of me, I’ve tired to google it but nothing came up. All I read was men who pleasure themselves too much. Idk I think it’s wierd I pleasure myself when I shower and he knows so idk he’s so embarrassed...
