Help plss !! I rlly f*cked up

Okay so first of all I'm a minor and being the stupid fucking idiot I am
I went on HER to hookup with some girl and a girl liked me knowing I was 16.

(she's trans btw, she has a d*ck, sorry I just don't want u to get confused about the text messages lol)

And I gave her my number so we can call each other and she made me really uncomfortable, just talking about her cock penetrating in me, I went along with it, I told her I didn't want to meet yet because my parents will find out
(Luckily I didn't give her my address)

But now I'm finally thinking clearly and someone willing to hookup with a 16 yr old is hella creepy and I'm not sure what to do ?!!

Should I just not message her and block her. Or should I tell her I'm uncomfortable or something and then block her??? JDKSJJS FUCKK WHAT SHOULD I DO
