Is it normal that the presence of my guardian disgusts me alot?

whenever i notice my guardian is around me i feel so uncomfortable.he preaches about things he can't do.most of the times he woos underage girls in my presence and it really irritates me.also when i request somethings from him he tells me he doesn't have it but if a girl ask him for that same thing he would
just give it to her.why?most of the times i feel like stabbing him.
