He acts like a baby?

My and my boyfriend have been together for almost two years and one day when we were having sex he started acting funny, and got really embarrassed when i asked about it.

Eventually he confessed me was a little?

( he feels like a little kid and acts like one)

And started calling me mommy.

It doesnt bother me alot , but its just kind of weird and new to me , i dont know how to feel about it , its cute sometimes... but its also kind of weird because hes so much bigger then i am...

Idk lol
