Chance's in percentage of still hymen of 27 working woman who is vergin. can she bleeding in first sex in 27 age ?

Yes: With an intact hymen at first sex, bleeding is still possible even at age 27. Not to worry, but see your doctor if any concerns.

Hard to comment: The hymen does not disappear as you age.Some are born without or lose it in a non-sexual event in childhood. If it is there and intact it would bleed during any penetrating event like intercourse at any age.
