Boyfriend likes ASMR but I think it's weird?

My boyfriend likes to listen to ASMR before he goes to sleep but not the kind where they make certain noises, he likes the ones with videos where a lady will record herself and acts like your girlfriend and then proceeds to tell you to have a good day, how great you are etc and it just weirds me out, I've tried to listen to them to see why he likes them so much (boyfriend version too) and I just can't get into them, why does he like it so much? And why does he still want to listen to it when I'm already affectionate enough to him?

We're having a baby in less than two months, how can I convince him to wean himself off of it since he can't be sleeping with earphones at night now due to a baby?

Also would it be too much for me to tell him to stop watching the girlfriend/sexual ones at night? I don't feel like it's appropriate to or necessary when we're dating

**Thanks for the advice, it's not hurting our relationship so I'll just leave it alone since he enjoys it// also didn't know they sold those types of pillows, maybe I'll get him one that way he's not wrestling with his earphones at night lol

** @Meh how are you going to say someone is judgemental but then judge them too? I was looking for advice so if you don't have anything helpful to say then move on
