Why did this happen to me PLEASE HELP *URGENT?

okay so when i turned 13 there is this "lady" in my church and he started a bible study for me and some of my friends to go to. we all went but she started to get a little touchy and ask to take us home etc. i am honestly convinced she is a ...male to female or just a crossdresser. i dont know what to do but i think she or he may be a child molester. seriously this is NOT A JOKE. my parents are concerned
