I just want to put my 2 cents in, no this is not normal, this is straight up child abuse and looks like it has been going on since you were very little. which explains why you would even have to ask. I think it also explains why you are being homeschooled, your folks are keeping you away from people who would hear or take notice of how you are being treated. similar to what happens to abused spouses, they are isolated from family and friends and completely dependent upon their spouse.

my son had a friend who was being abused by his step dad, he was 17 when he finally tried to get help and in his case child protective services did nothing, despite ph calls from teachers, the counselor and myself. I took him to the juvenile and domestic relations officers to talk to them, the intake officer came out to the lobby and asked me point blank if I would take custody of him. I went as far as petitioning the court but he panicked and changed his mind. the good news is that the mom kicked out/divorced step dad and the boy was safe. I'm not even sure she knew he was doing this to her son all that time.

I do hope you are able to find some help but it is true that your world could turn upside down, worst case scenario no one does anything and your dad retaliates against you for telling on him. Is there a safe place, relatives or some distant family friend you could go to if you need to get away?

Hugs to you sweetie, I will be praying for you
