If women were liberal with anal sex but staunchly held onto saving vaginal sex for marriage?

how would this change the nature of heterosexual sex culture? would guys then view vagina as the ultimate get-all and desire anal less as vaginal sex would then definitely seem the hallmark of femininity? How would this impact views on virginity? And would more women be successful in saving sex for marriage, assuming that there was no pain or feelings of dirtiness to be associated with anal sex?
