hymen has broken then bleeding is compulsory, my wife hasn't bled

First sex does not always lead to bleeding. A thin hymen will have a lower blood supply than a thick one. Sometimes the hymen does not rupture on first sex, and sometimes a fragile hymen will rupture without sexual intercourse. Occasionally girls have been born without a hymen. So while it is often the case that bleeding occurs with first sex, it is not always the case.
