Boyfriend and mom issues

It is so annoying when you want to tell your mom about your sexual life like a normal friendship between she and you, and she ends up calling you whore and bad words. What do you think about that? Btw she doesn't like my boyfriend too because he has long hair, piercings and tattoos, just dumb sh*t, also she likes to talk about him with her man and says some bad stuff about him when she doesn't even know him.
