Pushing his hand away

So lately I am not sure why but I have been pushing my boyfriends hands away or not letting him touch me or anything 'bad' (fingering, boob grabbing, ass grabbing,etc.) I either tell him to stop or push his hand away(like I did last night) I don't think about it at all I just stop him. Like I randomly feel as though he should stop, that I don't like it. It has begun like a month or so ago that I don't let him do those things and im not really sure why at all. He loves me and I love him. He and I used to do more 'bad' things but lately I just stopped letting him. I love when we used to do 'bad' things but now when it actually happens I push him away without thinking. What should I do? I do want to do those things pr have them be done to me but I don't know if there's something wrong with me...Can you ladies please help me figure things out? Thank you:)💗 ( I just wanted to mention I refer to them as 'bad' things cause my boyfriend and I randomly began calling them that, not because I feel shameful for them or anything. Just wanted to edit this post and mention that so there wouldn't be any confusion)
