My Aunts Secret And My Unknown Past

I was in a car accident when I was 8 and don't have any memory before it but recently I have learned some of my past. I have a very big family and it's majority females so when it comes to heavy work I get forced into helping. One of my aunts sold her house to move into an assisted living place and before it was sold all her stuff had to be packed up and sorted for what will be given away, stored or taken to the assisted living place with her. I'm one of a few guys in the family that lives close enough and is healthy enough to help with any of it so it was me, female cousins, one male cousin, some of my sisters, some aunts, and my mom at my aunt's house packing up her all stuff. She had a lot of stuff so it took a couple weekends to have the house completely packed up and naturally I would look through things while packing which is what I was doing one weekend when I found boxes full of tapes and some of them had my name, some had the names of cousins, and even a mix of names. Luckily the VCR and TV in my aunt's old bedroom hadn't been packed or even disconnected yet so I grabbed one of the tapes with my name and put it in. When it started playing it just looked like a home video of me at my aunt's house when I was 7 and since I didn't have any memories from before the accident I kept watching the tape. About 15 or 20 minutes in my aunt tells me to get undressed and I start doing it and am then standing around naked. I was completely surprised and confused at this point. The camera gets blocked and when it's uncovered again my aunt is standing in front of it making sure it's pointing at where I am then walks over to me completely naked sits me in a chair gets on her knees kisses me then starts sucking my dick. I watched for a little longer then started checking the other tapes and it's my aunt having sex with some of my male and female cousins, having me have sex with female cousins, me involved in 3somes and more with my cousins or her and my cousins and even more surprising with some of my other aunts. A few of my aunts from the videos were in the house that day so I told them I needed their help with some stuff I didn't know what to do with in the bedroom and when they got to the room I closed and locked the door and played the last tape I had been looking at and told them to start fucking explaining. They sat down and told me everything about how my aunt would have sex with me and some of my cousins and they would also get involved having sex with each other, their nieces and nephews, sons or daughters, and have us cousins have sex with each other and my aunt would film it a lot of the time and the amount of tapes don't reflect how many times they did or we did anything. They also told me that a lot of the family doesn't know anything about it, my parents never knew, and some of my cousins still remember while others don't but the ones that do remember were told to never talk to me about it since I lost all those memories and they didn't know how I would react. After being told everything I didn't know how I should feel about it so I grabbed the box of tapes and went home. I thought I grabbed the tapes as proof but now I'm not sure why I took them. I haven't spoken to my aunts or any of my family who's tried calling and texting me and I'm confused by it all especially since it actually turns me on seeing myself at those ages having sex with my aunt's and cousins and seeing them too. I don't know if or when I'll start talking to and seeing my family again. It's been a couple months so far.
