"Hahah" you laugh as you're in your boyfriend's trailer "What is it baby? What are you laughing at?" he comes closer and sit beside you

"I just found out that the most prominent hormone when us girls are on our period, is testosterone, so when we're acting emotional on our period, we're literally acting like a man..." you chuckle "Make sense honestly"

He looks at you shocked "ok ouch... But wait really?"
