Is this normal?

I can’t tell if this is a form of SA..? cuz this one person came over my house (said it was an emergency) after school, and kept trying to cuddle me in my bed and kept touching me even though I kept repeatedly tell them not to and it makes me uncomfortable, this isn’t the first time. they also touched my crotch a little bit too..? I’m still pretty uncomfortable but don’t know how to really express much (I’m pretty autistic) so I dunno what to do. Is it SA?
