Was I groomed as a child?

I was REALLY into a programme called Glee at that point. I especially loved the cheerleaders, I made myself a replica of their outfit from an old dress, and did a parody of one of the songs that they performed (say a little prayer) so I put my cheerleader outfit on, and danced around to the song like they did and uploaded the video to my channel, very innocent intentions. 

I began getting messages from men in my inbox, I believe they may have been old. They asked me to flash them, to put on an outfit which was even shorter, to be sexy. They repeatedly asked me to show them my boobs (I didn't have any, I hadn't hit puberty yet) I knew it was wrong, so I kept saying no, no, no. But they told me I was beautiful and it would only be a quick flash, that I had a beautiful body and they wanted to see my flat chest. So, after days of repeated compliments I caved, I fell for the lovely words and I did a video for them, I really quickly lifted up my top for them (about a second or two) and then put it back down and ended the video.

After I uploaded it, they sent me waves of compliments saying I had a beautiful chest and my flat chest was gorgeous, they asked if I would do the video again but for a longer time. I said no.

I remember having a quick look on one of the guys channel, he had hundreds of videos, all of them were of children, one of the videos were of three children (female) wearing only swimming bottoms, and their bare chests exposed (they were only 2-3) running around playing and having fun in a swimming pool. I didn't think anything of it at the time, but now I think of it, he was a peadophile.

The turning point was when I received a message from a random person who had seen my videos (which had become sexual due to request, but I didn't see anything wrong with it) and told me that they had called the police and they were on their way, this turned out to be false but it shocked me and I immediately deleted my channel. I am very grateful as I would probably have continued to listen to the men.

I was only 11-12 with very innocent intentions, I wanted to uploads videos of me dancing along to songs and it turned into videos of me flashing and dancing around in skimpy outfits, due to being persuaded. 

It hasn't affected me growing up, it was a long time ago now, but I always wondered if it what happened should be something to be bothered about or tell anyone about. 

So, from what you've read, was I groomed as a child?
