Is it normal that my girlfriend reacted like this?

My girlfriend is a radio dj. So she talks for a living.

Last Sunday - for the very first time ever - she told me that she is going to give me a blowjob. She hates oral but felt bad that I always pleasure her but she never done it for me.

So I got myself ready. I put on all kinds of scents and yummy tasty things so that she had a pleasurable experience too. My dick smelled like caramel, ffs.
I made sure that everything was trimmed and goodlooking.

So there we were. She was starting to get into a good rhythm and I started to enjoy it. I don't know why but then I started talking.

I said things like "oh yeah babydoll" and "I like that, do you like your lollipop cock?"

And everything was fine. She didn't reply because she believes it to be rude to talk with your mouth full.

So then my inner porn star took over and I said "oh yeah, baby! Work that moneymaker!"

She was furious.

She stopped and got dressed and cussed me; then left.

is this normal?
