Girl on girl. Different? Same?

I’m in my first girl/girl relationship and everything is still new to me. We are still figuring out how to communicate effectively and while trying to figure it out, sometimes we can get aggressive and physical. Nothing awful, maybe pushing each other that ends up in some bruising. I’ve always been in relationships with men who wouldn’t dare do anything like that. Is dating a girl different? Am I trying to convince myself this is normal? Am I one of those blind women? Our times that we are good are incredible, but does that make up for the physical trials?
