What if my friend is a boy asks what me and our other friend who is a girl are talking about and we are talking about period and he gets sad because he thinks we’re leaving him out

Okay so it's totally normal for guys to feel a little left out when you're talking about periods, because it's something they just don't experience in the same way, and it can feel kinda mysterious. You can explain that it's not about leaving him out, but about sharing experiences with your girl friend that are super specific to being a girl and having a period.

What to say

You can be really chill about it. Like, "Oh, we were just talking about period stuff. It's kinda a girl thing, you know? Like how you guys talk about [boy stuff he talks about]." Or you could even share a tiny, super high-level detail, like "Yeah, we were just talking about how annoying cramps are sometimes." This isn't about giving him all the details of your period, but just enough so he knows it's not a secret about him.

Why it feels weird

Sometimes guys might feel a little awkward or confused about periods because it's not something they learn a lot about, and it's definitely not something they experience in their own bodies. So it's not usually about them being mad at you, but maybe more about not understanding. It's super cool to just explain it simply and honestly, without making it a big deal. You could even ask him what he thinks you were talking about to show him you care about his feelings, and then clear it up.

Keep talking to your friends

It's really important to have those conversations with your girl friends because it helps you all feel less alone and understand what's happening with your bodies. And that's a good thing! You shouldn't have to stop talking about periods just because a boy is around, but you can definitely make sure he understands it's not personal if you need to talk about private girl stuff sometimes. Having open conversations helps everyone understand each other better, even if they don't experience the same things.
