I agree. But the claim in question is not whether she gave birth, but whether she gave birth "exactly like" your birth and mine. And the Bible does not say that Christ's birth was "exactly like" your birth and mine.
Virgins are virgins because they haven't engaged in sex. The aren't virgins because they have intact hymens.
The two are not mutually exclusive.
Will you agree that a horse-riding young girl whose hymen ruptures is a sexually experienced young lady?
Of course not. But I never claimed otherwise.

She gave birth means she gave birth. Any understanding you add to that other than the normal meaning of those words would be the addition.
