My girlfriend f25 is fwb with my best friend / her ex in high school. They have been fucking for about a year now and I’m starting to think they are rekindling their old relationship now. Reason why is bc she NEVER has sex on her period with anyone. That’s been an off limit thing since we’ve started dating in 2018. Also when they fuck, they’re typically aggressive and wild. But recently when they fucked, she was on her period and it looks passionate as hell!

Am I overreacting and should let them keeping fucking, or are they starting to get more into intimate sex rather than aggressive and wild? I have video to prove it.

Sorry this isn’t much of a story, but more of a rant
