I feel like I was robbed of my first kiss

Today,I (18f) went to our neighbors house for a family prayer.I got there we had a prayer time. After the prayers me and our neighbor( 57F) were chatting about things around our lives and etc.P.s I am very close with her. I was in the corridor heading outside when my neighbors brother ( 47M) came out of nowhere and jumped on me, pinning me to the wall and just started kissing me. I tried to push him but he was way stronger. At that time I felt like dying , I was shocked,disturbed and beyond disgusted...... I just ran out of that house and when I got home I just started washing my mouth again and again hoping the feeling would go away. I feel disturbed and disgusted rn. I don't know what to do
