Am I being too sensitive?

This really bothered me. So I’ve been dating this guy for a month and every time I send him sexy pictures or cute videos on Snapchat he doesn’t seem to like it.

Today for example I sent a cute video with a filter and a song in the background and his response verbatim

“Okay I already know that your pretty but would you stop with this bullshit” ...

I just don’t know if I’m being overly sensitive but I felt unwanted.

I told him “this isn’t even for you, I like taking pictures but if it bothers you that much I’ll stop” and he didn’t even respond to that.

What should I do and how to handle this? I’m new to dating and quite young

Thank you :)
