First, Christ is known as perpetually virgin although explicit dogma is unnecessary to proclaim as He has no children and there has never been a question of His virginity (Dan Brown novels aside). The Gospels also clearly record Jesus suggesting perpetual virginity to male disciples for the sake of the Kingdom. So the notion of of virginity as a sexist proposal only targeting women is completely unfounded

Moreover, I fail to see how championing a form of life (virginity/consecrated life) which results in women living totally independent of men, free of children to care for, often times pursuing years of study, integral service in the community, and providing for themselves achieves the ends of sexism. A proposal of marriage as the only acceptable life for women (a la Martin Luther) can be contrived as a sexist's dream of permanently tying up women's existence to male provision, child rearing, and a general stifling of their education. 

Maybe you can explain your claim a bit more
