to be affection or not to be affectionate

Sa
I find myself becoming annoyed/irritated when a guy a date forces me to hold hands, hug/cuddle, and or make out/kiss. Am I mean??? I feel this has been a recent thing (like a year 😂) for me starting to feel this way. I don't know if it's because of my PMDD or if I've just changed the way I show affection. 
I've been in seriously relationships where I've given and shown my love  . Worst part is I should say something about how I feel. I just don't know how to approach that I'm not into showing affection or I don't want to hold hands.... 
I read that I may be a thinker not a feeler
Anybody relate or have advice?
