AITAH for putting a hard limit on my relationship?

Sorry if this post is a little hard to understand,this is my first post here and English is not my first language so sorry in advance.

​

so I've been dating this guy for about 4 months now,and from the beginning of our relationship I've always told him how I'm uncomfortable with sexual comments about other women yet he always ignores it, everyday he makes at least one comment that makes me uncomfortable and I have to remind him about how I've already told him how uncomfortable it makes me and to please stop doing it.

​

At first I didn't really mind if he slipped once or twice but he does it constantly now and he has openly admitted that he sometimes does it to annoy me or make me mad.

​

Today was the last straw,we were playing some co-op game when out of nowhere he said how it was a pity I wasn't a certain race because it really turns him on,now I might be the asshole here because I blew up on him and started going on a rant about how he does this everyday when he knows it makes me uncomfortable and insecure,I ended up telling him that he either stops it or I'll straight up break up with him,that if he didn't like it he was free to go but I wouldn't be putting up with it anymore.

​

He started saying that he will try to stop but he thinks that it is a little extreme.

​

I know this is a little dumb but I don't have anybody else to talk about it or get a second opinion from.

​

So AITAH or was this a normal reaction?
