Bathtub tap/ showerhead masturbation

So I recently opened my legs to the bathtub faucet and I’m stunned! It’s amazing, where have I been all my life?! Anyway, I was wondering how safe it is because I’ve read that it can mimic Douching since the water is falling over your vagina even tho I aim for my clit but of course it falls down to the vagina right? So Can someone tell me how safe it is and how often to do it? I don’t want to catch an infection because of it
