Sincerely asking Fujoshi

For straight relationship, Is Significant Other know you read yaoi?
Or r u hiding this hobby from them? How do you do so when you always with them?
If you from a conservative country, do you come clean about this hobby?

I'm from conservative country. Sadly Lgbtq isn't widely accepted here. Finding someone who simply has open minded is difficult af. When dating, I have no problem being a fujoshi. But for marriage, how can I able to leave my only happy time with BL?? I'm this old, one of the reason rn I didn't chose marriage because of this concern. Help, If you have some experiences.
