no bleeding does not always happen. if the woman has an thick occlusive hymen a traumatic tear during an initial intercourse can cause some bleeding but many virginal women do not have this type of hymen. hymens will stretch over time from using tampons or they can just atrophy (shrink away) from riding bikes exercises etc. so bleeding may never occur.
does a woman always bleed after 1st time sex? . is this a myth? i never did bleed and wondered if sometimes you don't?
