Is it creepy that my boyfriend said I look so young it's like dating a teenager?

Yes that is a little odd. not creepy but odd.
I am assuming that this guy is much older than you? You should tell him wait until I am 42 and look 27 A-hole... I imagine that he was teasing because guys are this way for sure.
You should speak with him about it. Sometimes that is a way of saying that you are immature too. Keep that in mind as you could have a "teenager's Personality"... you act so young etc. Good luck with that.
I think you should ask him and tell him to be honest. Cause its not creepy but rude

Maybe you just look young and it’s no big deal.
It needs a bit more context. I’d be concerned if he sounded turned on. But if he seemed apprehensive, or awkward about it, not too much.
No it's better if he said you look like you play bingo and shuffleboard granny.
He was just trying to Compliment you, If you keep taking things in a Negative way he is going to find you Unattractive.
Sadly, there are a lot of men that have a fetish for teenagers.
Yes, that is creepy
maybe he's into that.
that is a good thing
Is it true?
