I (F23)'ve been in a relationship with this guy (M33) for like a year. When we started dating, after a month of getting to know each other we went to his place and did the deed. Enjoyable experience overall. BUT, after he was done, he removed the condom and...with very expert gestures, proceeded to drink his junk right out of it.
I was shocked and confused. In my head I was like "Yooo man, wtf????". He was my first partner and like...I wondered if that was...kinda normal? Common? Idk???
Since I used to be a people pleaser, I managed to hide my shock and disgust, and simply asked him: "Why did you do that?"
He answered me, as if it was the most obvious thing in the world: "It's a lot of kiloJoules of energy, I can't waste them".
I was even more confused. I was literally speechless and what was being a very nice and romantical night managed to become a weird and kinda awkward situation.
To make things worse, he even stated in a very dramatic tone: "I will never allow anyone to eat my semen". He said that like his junk was something precious...like...if someone would ever get access to that...it was like, being able to steal his soul??? Idk. It made no sense. And also, dude, nobody here is trying to steal ur precious cum, ugh.

Btw, he wasn't drinking his cum in a kinky or erotic way or idk, he did it like it was an extremely serious and important deal. Why drinking ur own cum must be so dramatic???
We kept dating for several months and everytime we had sex, every. single. time. he did the same thing.
I started to become very concerned, since usually inside the condoms there's usually some lube...I guess? He even complaint about the bad taste of the lube or the latex the condom was made of (the taste of his own cum somehow didn't bother him at all, good for him). And even if usually lube is not that toxic, I think that consuming a small amount but very often may not be the healthiest habit. Also his breath right after this "ritual" almost made me throw up all the times, since he even refused to brush his teeth afterwards. "I didn't chew, I swallowed it in one gulp, so I don't need to brush my teeth". Ew.

I tried to discretely make him understand that his habit was grossing me out, by saying out loud "EW" or by covering my eyes, but he didn't got the clues.

A year passed by. I had enough. I tried to confront him, but nope. He was unmovable. Neither the fact that his passion for his own cum was making me a little uncomfortable, nor the fact that imo eating lube could be harmful made him stop.
He then proceeded to get mad. He stated that he wasn't doing anything wrong, that he just didn't want to waste "precious substances from his body" and that I was making a scene for nothing. I told him about his breath and he straight up accused ME of having a bad smell??? I told him that by deflecting my accuse he was just making things worse, but then he interrupted me and just told me I was insufferable. Then he just left.

He was extremely angry, I've never seen that side of him. I'm sure that he will tell me to pack my things and to leave.

So rn I'm mad, confused AND scared about his behavior.

TL;DR: after the first time me and my partner had sex he drank his own cum directly from the condom. I was disgusted and after a year I asked him to stop. He got mad and I think he's about to leave me.

EDIT: OMG. Well, I was right about being freaked out by his behavior having read most of the comments... Anyway pleeeease no judging about the fact that I've stayed with him for over a year (I'm really ashamed about it), the situation was very complex for me. But to cut it short, let's say that I have very low standards and not a lot of self-esteem :^(
