Do guys like giving hickeys or is it because they're overwhelmed, and that's how they relieve their urge? Do y'all mark someone on purpose?

I let my ex drive me home. He's been seeing and liking other women. He even thought about dating other women again. I don't care. When he got to my house, he kissed me and started to kiss my neck.
I told him not to bite me.
He did it anyway, and I let out an ouch. I told him he bit me, and he told me he knew, and he did it on purpose.
When I got in the house, I had a hickey from what he did.
I know he's not in love with me
I just want to know from a male's perspective why you think he did that?
And is this a common "in the moment" occurrence?
The Pic is what kind of hickeys he did while we were dating...

I do want say before we dated I was breaking it off with my friends with benefits and my friends with benefits left a hickey. My ex saw it. He was mad and didn't talk to me until I made him. He was mad that I went back to him after our 1st date. However we been through the relationship phase and are now exes, he shouldn't of bit me in the car after I told him not to. Why, if he likes someone else?
