That would totally depend on the girl.
Oriental foot massage from a trained, slightly-built masseuse could be invigorating. Inspiriing, even.
But shiatsu from Melissa McCarthy? I think I'll pass.
Is it weird to like being stepped on by a girl?
Weird? Yeah maybe. Bad? Most likely not unless you are getting to the point where you are putting yourself at risk. As long as it's not putting you or anyone else at risk, there's nothing wrong with liking weird things.
