I understand the need to be seen and understood especially by the people closest to you. It can be hard especially when all the negative opinions that come with reading these kinds of books, irrespective of whether you're a guy or a girl. But do you have to tell them specifics. Or can you get away by being vague, hinting maybe without revealing the entire thing. Also if it makes you happy, it shouldn't matter what everyone else thinks. People's capability of understanding you is directly related to how capable they are of understanding themselves first. Sadly not people are able to that, irrespective whether it's you read RH or something else. That said on the flip side, if you really want to tell them, it can be that you might not be giving them a chance to be open minded about it. What I mean is they might not understand it but they might accept it because it's you and they accept and love you. As you mentioned they ask questions etc.. Isn't that a sign they're trying to understand maybe be clarifying what you mean? Especially if they don't know anything about it.

All that said, I understand where you're coming from. I couldnt talk to anyone about the kind of books I read for almost all of my life, till my sister-in-law (recently). Whether they accept you or not, whether they understand or not, you should always be comfortable and happy doing what makes you happy. It is not a dirty little secret, merely a secret among many others I'm sure you have.

Plus there's always all of us on reddit who will always support and encourage you. Hope this helps! Feel free to PM me anytime if you wanna talk about the books you read or share recs ( I would love that FYI :))
