I had first time sexual intercourse but did not bleed, is it possible that i did had my hymen intact but it did not bleed when torn?

Yes, for sure: Many virgins do not bleed. The shape and size of the hymen can cause this - also hymens can be broken from other normal life activities in some girls - don't worry and if your lover is distressed refer him to web sites that will explain this phenomenon. Assure him that his trust in you is at least as important as your virginity. Best wishes.

Not a problem: The hymen is an interesting structure with lots of variability.You can be born with little or no hymen, a thin ridge, thick or thin, one with several small openings or a none at all (a real problem). You know whether or not you've had prior intercourse & that is enough.
