Why are women not allowed in Hanuman mandir ?

From past 2 years I have been chanting the "Hanuman Chalisa" on a regular basis and also visiting the Hanuman Mandir and I noticed that women refused to enter the premises of the moorti ,when asked this to my mother she replied as hanuman ji was a baal bramhchari he didnt marry so women are not allowed to enter the mandir . If so why are women not allowed if being bramhchari is the reason then males should not be the one to enter expecting that they will not get married. Please answer this question ... :) :)
