Philip Jenkins, here, who notes the Feast of the Nativity of Mary on September 8th:
As recently as 1950, Pope Pius XII stated that “we pronounce, declare, and define it to be a divinely revealed dogma: that the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory.” ... [F]or most Protestants (and some Catholics), the ideas I am describing – the whole Marian lore – is so bizarre, so outré, so sentimental, and so blatantly superstitious that it just does not belong within the proper study of Christianity. If anything, it’s actively anti-Christian. Even scholars prepared to wrestle with the intricacies of Gnostic cosmic mythology throw up their hands at what they consider a farrago of medieval nonsense. ... [T]hat response is profoundly mistaken. If we don’t understand devotion to Mary, together with such specifics as the Assumption, we are missing a very large portion of the Christian experience throughout history. It’s not “just medieval,” any more than it is a trivial or superstitious accretion.

That's right. The perpetual virginity of Mary is no more outrageous than the virgin birth of Christ, except that for Protestants it conflicts with the evidence that Jesus had brothers during his lifetime. To them the Romanists engage in special pleading when they say that the plain sense of these texts isn't the plain sense and should be understood in the light of the much later "apocryphal" evidence which maintained Mary's perpetual virginity and that his "brothers" must have been only his nephews or cousins.
More to the point, however, missed by most commentators, is that Jesus' rejection of normal family relationships is paramount in the Synoptic narratives mentioning his brothers and mother, and is rooted in his apocalyptic worldview of an imminent end of the world. Being tied down by a wife and children or a mother and a father and siblings, or a job or possessions or the cares of this life generally, all will hold you back and keep you from escaping from the wrath which is to come, and come soon. To repent is to turn your back on all this. The historical development is that when this Apocalypse he preached failed to materialize, this part of the teaching was transformed into an idealization of celibacy and virginity.
