Petty Grievance

Hey reddit. I have a petty rant that I need to get off my chest. I have this guy friend who is pissing me off and I know I'm being too sensitive but I feel it's worth ranting about to try to just get it out somewhere.

So he generally identifies as a guy and has a male reproductive system. While I know most males do not function on a monthly cycle, he has claimed that some men have hormonal fluctuations monthly similar to a period. I did some research and it appears to be an actual thing, which who am I to doubt to begin with. I don't have that system so I don't know what it's like. He says he experiences these symptoms which I completely understand. For lack of better (more eloquent) words, he gets really horny for a week or two of the month every few months and is very open about it with me. That's ok, though it bothers me sometimes as someone on the ace spectrum who doesn't love sex but I've been working on setting boundaries for that.

Here's what's really getting me though. When he's at this time, he calls it his "ovulation". This pisses me off but I don't know why exactly. It shouldn't be that deep. For a little context, I am AFAB and have really horrible PMS symptom, primarily mental but some physical as well. On multiple occasions I have thought of seeking psychiatric assistance around my ovulation and primary pms time because it's gotten really bad. A lot of times I think I'm genuinely losing my mind and it's caused some serious problems. I also struggle physically with some joint pain that I believe is related.

As silly as it sounds, him calling it his "ovulation" or his "period" really bothers me because the actual experience of someone with those cycles is so miserable and he's always complaining about it but it's something I deal with monthly on a much scarier scale. I think I'm being a little toxic thinking this way because everyone's pain and discomfort is valid, but getting it out is nice. Maybe I'll bring it up someday, but I bring up a lot of things that bother me in this friendship in an attempt to be communicative and I'm scared I'm just a bad friend at this point. I'm not sure what to do. Am I being way overdramatic? Is this a silly thing to be mad over? Is he actually doing something wrong or am I just amplifying the issue in my mind? If anyone has any thoughts, I'd be more than happy to hear them.
