Just Some Questions About Fujoshis and Yaoi

Okay ngl I'm probably a bit young to be on this website but I've seen so many discussions about fujoshis and yaoi. So I just want to ask some questions.
1.) Is it okay to read stuff here under the yaoi genre?
2.) Is it okay to read yaoi at all?
3.) Does yaoi fetishize gay relationships?
4.) Is it okay for me to read it if I'm not using it to fetishize gay relationships?
5.) Is it okay to read yaoi if I know yaoi and real life are two separate things?
6.) Why is calling yourself a fujoshi so controversial?
7.) Due to the controversial subject should I stay away from identifying as a fujoshi?

I'm not trolling I'm just curious and want to make sure I'm not offending anyone or doing anything wrong. Thanks for answering!
