Is this wrong?

Ok so I'm 14. And since I was 12 I've read a few 18+ books(My mum has no idea and I would like to keep it that way because she is a Jehovah's Witness and is a bit of a control freak and I'd feel uncomfortable her knowing as I'm not close with her at all) they were 18+ All because of the language and sexual content. NO that is not why I bought them. He reason I bought them is because I fell in love with the characters. And the author is now my favourite author. But these books,as 18+ ones, they are obviously meant to make women moan at the thought and probably end up masturbating while thinking about these books and reading everything. They have no effect on me. Which I'm really happy about but is t bad that I'm reading 18+ books even though I'm 14? And even though they have no effect on me? Also think about it. Everyone is open to language in this world you can't get away from it! And most films or TV programmes we watch has sex in it. At 14 I know what sex is and what happens and I know how you can kink it up as all but I honestly don't think it's bad for me to read 18+ books if they have litrelly no effect on me. What do you think? 
Some examples of 18+ books I've read:
*Stepbrother dearest by Penelope ward
*My Skylar by Penelope ward
*Sins of Sevin by Penelope ward
=Yeah all of them are by Penelope ward, she is a brilliant author and I love her books and am excited about her new ones. 
And not to be rude but 
•IF YOUR GOING TO CRITISISE ME, JUDGE ME OR BE NEGATIVE AND BULLY ME. THEN FORGET IT BECAUSE I'LL BLOCK YOUR COMMENTS AND IM SURE YOU COULD BE DOING OTHER THINGS WITH YOUR FINGERS OTHER THAN TYPE CRAP TO INSULT ME. 
Thank you😊
