Should I tell my mom that I like Yaoi?

I've been thinking this question for months if I should tell mom that I like Yaoi. My sister and brother found out that I'm watching those Thai BL Series and read Yaoi mangas but they are okay with it. Also Mom approved my sister's relationship with another girl. My mom happily welcome my sister's gf. If mom is okay with my sister's gf maybe she can approved me liking Yaoi? But I'm a little scared in telling mom that I like Yaoi:<
