<human>: I met my boyfriend (let's call him John) on Tinder over a year ago and it only took us a week to fall in love. I know for a fact he is the one for me and I love him with all my heart. He loved me too, and that's hard for me to say because I'm always one to assume everyone hates me. Our relationship is like a movie, started perfectly, going perfectly, everything is amazing. Except me. 

I grew up with a little brother and boy cousins and we were always rough with each other. We would watch UFC and me and my brother even took Tae Kwon Do. Naturally I grew up hitting and kicking jokingly and I carried it on to my (almost) adult life.

My boyfriend was a black belt in Tae Kwon Do and he was rough too, but I feel like sometimes I get a little too rough. I'll smack him in the arm, or kick him, or bite him too rough. I always catch myself and ask if it hurt him and he always says no, but I feel like I do. 

I feel abusive sometimes, but I don't do it on purpose. What can I do??

Can you condense the text into a few key points?
<bot>: I get too rough with my boyfriend sometimes, he says it's ok, but I feel abusive. I don't catch myself most of the time. Help.
