What does it mean when a guy is talking mildly sexual stuff in online dating?

I messaged this guy first a few days ago because I thought he looked really cute and he's been looking at my profile a lot and all and he got so excited when I messaged him

We've talked for a few days now and he's already made some remarks that I found hilarious though probably because I like him for example he called my horse lucky because I ride it and when I told him about my favourite colour he asked me if I also have lingerie in that colour lmao

I'm new to online dating, are a lot of guys talking like this? I don't mind in this case because I like him and I already said we'll have a sleepover I just wouldn't have expected that from this guy to be honest because he still to me seems like a really introverted shy person like me
