My bf did spit in my mouth

Yesterday me and my bf had sex and its so far the best sex we ever had!

We had an argument and we were about to break up , we decided to talk things and we apologised to each other’s

Anyways, we fucked and it was so rough! Like he was so mad with me he wanted to fuck me so roughly, the thing is I liked and enjoyed it!

He then for the very first time spit in my mouth repeatedly while inside of me! I never thought i d like it! But i did! But i don’t know why he did this for the first time after a relationship and sex of 10 months. He also asked me to lick his balls for the very first time!

When we finished he said he enjoyed it so much and asked me if i did too! I said i did and asked where the new thing( spiting in my mouth ) is coming from and he only laughed!

The thing is i googled that and people are saying that a man spit in his partner s mouth to show her she is his slut!

Does he see me a slut? And why never showed me this side before? And is it ok to like my partner spitting in my mouth while fucking me!
