Is it normal for this to happen

I am 35yrs old and since the age of 21 my dad and his twin brother have been my lovers they took me out to a club and we got super smashed I don't even remember getting home what I do remember is when I came to my dad was under me and my uncle was having anal sex with me I'm trying to break away and my dad grab me around my throat and said your my daughter and every part of you belongs to me I'm still trying to get away he slaps me and says be a good girl and please your father instantly I got extremely wet I'm not thinking to myself this isn't right my dad and his twin are raping me and at the same time starting to like it after they were done I ran to my room and starting crying I couldn't believe what had happened a few minutes later my dad knocks on the door and said can we talk I said yes he said listen this has been going on in this family for years and its perfectly ok to happen he said his mom was in a incest relationship with her dad he said the reason it happen to me was because it was my time he went on to say call your sister and she'll explain he kissed me and said your a good daughter I called my sister like wtf is going on she said oh you've experienced what its like to please dad I'm like this isn't right she said sister its been happening for yrs and its something we all have to do so I continued with it I told one person and was told that I was brainwashed into continuing this I like it and I don't I like it because it feels wonderful and I don't like it because I think this is wrong I've been thinking I need to seek some professional help because I'm confused on what to do
