can doctor tell if your virgin or not? what if you broke your hymen by riding a horse, could they still? is there a difference by being a not virgin by having sex and by other activities like sports...? could they tell the difference?
A doctor can't tell why a hymen is no longer intact, just that it either is or it isn't.
And the only way to not be a virgin is to have sexual intercourse, that's how it's defined. You can't lose your virginity from 'other activities like sports'. You can lose your hymen, but not your virginity.
