Is tickling abusive? ( Or can it be )

My SO is very rough and strong, sometimes he tickles me out of nowhere and I can never get away from him. A few years ago, I had actually banned tickle fights because he always left bruises on me, they hurt alot, I couldn't do certain things. From than he was okay but now he's become rough again. I'm not really worried about myself and this because I'm always hurting myself anyway but now we are ttc, I don't want him doing this to our child. Maybe he doesn't understand his strength?????
