Awsome, but I have a request

So this app is awsome! I love it, but I do have a request. So I’m a trans guy (ftm) and I still have my period, so I was just wondering if there could be a secret chat for trans guys? I just think it would be nice to talk to others about this? Anyway great app!🖤

Whats the big deal?

Honestly i dont really care if facebook knows when im having my period. I dont care if everyone knows im on my period, in fact i would like them too know.
So people need to stop freaking out over the fact that our data is going to facebook.
This is a great app over all
