I have no clue where to post this so I’m doing it here

For context I’m f16. I had been friends with this guy online for about 2 years, we had been talking since I was 14. We would do freaky things like rp and stuff and I guess I liked it? He told me he was 15 when we met, but I recently found he was actually 18 when we met (he is now 20). I don’t know if it counts as being groomed or whatever else this would be considered, but I feel disgusting for wanting to go back. I’m confused and I’m scared and I don’t where else to post this. Thinking back makes me wanna throw up because he would get off on things like me calling him “daddy” or him telling me I was his “good little girl”. Any answers are appreciated!
