Period talk with fiancé

Okay so last night I was talking with my babez and we were talking about periods because he 🤦🏾‍♀️ didn’t know what exactly a period was for like he doesn’t have any sisters so it was actually never talked about in his family. Plus I’m on my period so it wasn’t to random lol it was weird to talk about with him cuz I’ve never talked about my period with a guy unless it was my GBF (gay best friend) so talk to him bout it and like everything was like 😬😬😬 then I was like the worst part is when you stand up and it’s like a water fall of blood and he starts laughing and said waittt whattttt I was like never mind nope to weird to talk about. Do you guys talk your S.O. bout your period orrrr no lol
