I'm not sure 🤔

Not that long ago I was 17 at the time and my partner was older Has anyone had experience with this I told my partner I didn't like anal but hed just sort of start doing it I dont know if he thought I wouldnt notice I dont like it coz it hurts alot and I sed could we not but he sed just for a little bit. And I cought him filming me whilst we were having sex I told him to delete it but he did say it was just for him. but It just constantly going round my head

Relationships are real grey areas I dont know what's normal really
