It might be ok because I consented initially? He could not of noticed I didn't want to (when I was moving my head away) It only lasted 2 seconds or something? He didn't carry on the final time I moved away? I cant remember it all?

It might not be ok because how could someone not see moving away as a sign of no? I cant help feeling like he knew and he was seeing how far he could go (he was very manipulative and knew I was vulnerable and would do ANYTHING for him) and after he pushed it in for a few seconds and I moved away, he knew he'd pushed it? Maybe he realised I realised what he was doing was wrong and that's why he stopped? (BUT doesn't that make it ok?) Maybe he hoped I wouldn't notice?
