Girls, Are you tougher/stronger than your BF? Do you care?

I'm a skinny guy who has always had difficulty gaining weight or building muscle. That's just by body type. Almost all of the girlfriends I have had have been stronger than I am and many tougher as we sometimes play-fight and I quickly realize if it were serious, she would kick my ass.
For some it's been a problem. One told me she didn't want to go out clubs at night or walk in certain areas because she said she knew if anything happened, she'd be the one defending us. I mean I would certainly do my best but realistically, she was right, she would have been much better at it.
Another said she liked it because she knew I wasn't a threat to her and would not get abusive.
Just curious what girls think about dating guys like me (truly) since most will SAY it's no big deal.
