is this okay

so last year I went to a family friends house and the only people who were at the house was me and their son (16). We were watching youtube videos and laughing then all of a sudden he got on top of me and started dry humping me (we both had clothes on). I was 13 at the time and I thought I was really special. Looking back I feel disgusted and guilty about how I let that happen and why i didnt stop it. I cant stop thinking about it
i'm gay btw and I have seen the son multiple times at family parties since and its like nothing ever happened.

He molested you, probably the reason why you are gay now is because of that experience

huh

Lol what?

That’s sexual assault. Talk to him about it while you’re recording on your phone and if you can get him to admit it then go to his family

we both had clothes on so is it sexual assault? and I dont know if hes forgotten about the experience or not cos when we see each other at family parties we talk to each other like it's normal but I can just tell it isn't the same

It was an assault of a sexual nature - dry humping as you say. So, yes, it is sexual assault.

Are you really that green?

like after I left his house I felt so special. Like I know this is gonna sound weird but I thought he loved me but now I feel so disgusted and guilty on how I just let it happen

It was in the moment, you probably weren't entirely sure what was going on, it wasn't expected, you didn't consent.
Don't feel disgusted at yourself as he did it to you out of the blue.

I know it's easier said than done, but please don't blame yourself. You were 13, this guy was 3 years older than you (and three years is a huge gap at those ages), and you couldn't have consented even if you'd wanted to. This whole situation is on him, it is entirely his doing and his fault, you certainly don't have anything to feel guilty about.

If you're okay with still being around him at parties etc then that's okay, it's also okay to not feel comfortable in his presence. You need to do what's best for yourself.

I doubt he’s forgotten sounds like he’s hoping you forget. Confront him 100%

I want to but i dont know how
