“When did Protestants start to regect the idea of Marys perpetual virginity?”
If you count Tertullian as the first Protestant, somewhere between 160 and 220AD. The official Marian doctrines were established by the Roman Church 300 years later, at around 541AD.
So a long time.
I would opine the new protestants started rejecting these (and other) docrines with the advent of the printing press.
Around the year 2 or 3 A.D...When the other kids started showing up...

When they got the opportunity to read the bible themselves perhaps.
I would guess after the Council of Trent made it anathema to not believe it.
