Fiance following pornstars on Twitter

So I'm currently 25 weeks pregnant (FTM) I asked my fiancé if I can use his phone for Netflix just in case he falls asleep, he said yes and he shortly did after. While looking for something to watch I saw a notification from Twitter saying that some porn star started following him then I just ignored it until another notification pop up saying the same thing. So I clicked it and his home twitter is just nonstop posts of porn and nude videos. I just threw his phone on the bed and instantly started crying my eyes out feeling so insecure. My question is should I bring this up to him when he wakes up or just ignore it thinking this is what guys normally do?
