If you meet a man online, you make out in his car, he asks you to have sex, you say no, then he pulls your hand to his groin and basically rub himself with it?
You were frozen. So you basically just let him do it.
However, you start "dating" him. Which basically means meeting up, making out in his car. You never consent to sex, but did some stuff.
Your friend (another guy you tell this to) tells you you're a "cock-tease" because you don't want to go all the way.
This happened many many years ago.
