TW!! Grooming?

So I’ve been gone into one of my deep depressive episodes and I’ve recently been dwelling on this memory that is stuck in my head. I’ve never shared this with anyone from embarrassment…but lately I’ve felt really gross about this and need to at least write it out for someone to hear.

We had a family friend staying with us when I was 15/16 who was kinda the “cool guy” that always hung out with us kids (my brother and our friends). Well me thinking nothing of it at first there would be times we were alone and I confided in him with a lot of things a young girl would have questions about… I truthfully do not remember what led up to it but for some reason he had asked to massage my back and I agreed. This happened more than once just, what I thought was, a normal back rub. Eventually it escalated to him getting lotions and going further down and around my thighs and clearly near my crotch. After this he felt the need to ask how I kept myself - proceeding to tell me how I should keep my pubes so that I didn’t attract the wrong type of guy, explaining the circumstances for each “style”. He began to get rather friendly and even slightly possessive of me after a while, telling my brother when he could and couldn’t come in my room while in there. Right before he had been kicked out (for unrelated reasons) he had been asking to keep his book bag in my room while he was out of the house. I didn’t think anything of it although he had his own room with locks? Anyway, I was once getting ready to get dressed after a shower and panned over to his bag and there was a light and camera lens sticking out of it. I never confronted him as he was like 30 something and I was again 15/16 but that’s always stuck w me bc i could never pinpoint why I didn’t feel right about any of it and being a little older now I can see that none of it was okay…
