Nudes (is this normal)

I said something earlier but this is also bothering me, is it okay that my boyfriend HAD nudes of other girls and wanked to them before me and him got physical like at all. He wasn't getting nudes off girls, they were saved on his phone. Idk if that's a douche thing to do? He's deleted them after we started to but I'm just curious if u think that's okay? I'm not that bothered, I'm jw.
