Is it normal to sense "sexual attraction" by a family member?

Growing up, i lived with an aunt and her husband. But for the most part he was always in jail for drug stuff (not doing it but selling. When i was 12, he'd been out for a few years. And i started noticing that whenever i'd get in trouble (regardless why) it was quite often (but not ALWAYS) just after i'd get out of the shower that he'd start yelling and stuff. A few times (like normal parents) he'd knock me down or whoop me. But i'd always be wrapped in a towel. I remember once.. I wasnt doing well in school and when he got home that night.. Just after i got in the shower he had called me to the table and after sitting there in my towel listening to him he started saying how he hated beating me and how it hurt his heart. And how hed do anything for me like kiss my ass. To which he then beat me and then literally and i do mean literally kissed my ass.

Ialso remember one day after school or during the summer (cant remember which) i had just gotten home from whereever. And he was giving me the "puberty" talk. And thought it was time to "show me how to wash myself properly". I was maybe 14 or 15 and had washed myself all my life...so this was odd. But i get in the shower. Thinking he was tryna be fatherly. He grabs a wash cloth. Washes me entire body but washed my private area a little hard. After a brief demonstration he left.
That just struck me as odd. Never sat well with me. But i thought it was normal.

As i got older maybe 16 or 17 i distinctly remember not being able to talk to my aunt about anything. She was always mad at me. So i spoke to him. But then hed twist my words somehow and boom im in trouble. And i remember my aunt more than once telling me to "go talk to him. Since u like him so much" it was more the way she said it that stuck with me. Also i overheard her on the telly one day and was obviously talking about me. I was her favorite topic. And i heard her say something like "she'd probably fuck him anyway".
I kinda got that vibe off of him too . but i was young and just figured he wasnt like that and she was out of her mind and insecure about her weight.

I do remember him telling me not to give myself away cuz i was a beautiful sexy young lady and no one was worth my time. It always made me feel odd when he'd call me sexy.

Sometimes this pops into my mind. I wanna pass it off as normal but im not sure if it is.
IIN?
