What do you mean? That's a pretty good rule of thumb of whether or not a girl respects you or if she is looking to make you her errand boy/attention dispensary. That's not even something that you necessarily learn online, your gut should be screaming at you if you are being made someone else's bitch, it literally comes as a package deal with having an XY chromosome.
There is enough pussy out there that you have no real reason to put up with women who try and have you wrapped around their fingers like that unless you have some kind of humiliation fetish, or extremely low self esteem.
