I was a virgin and my bf always finger me hard by reaching deep always he did atleast 50 times when we met then he tries to insert his dick inside me i was fully wet aroused the dick slides in, he started asking that i wasn't a virgin i didn't bleed?

The normal opening in most virginal hymens is a centimeter, +/- in width. Any finger other than a babies, will stretch out the hymen and or tear it to the point it will not bleed with regular intercourse. In the situation as you describe it he should NEVER expect you to bleed with intercourse. He ended that possibility with the dozens of fingering episodes.

Your partner does not seem to be very knowledgeable about female genital anatomy. This amount of fingering would destroy the hymen, and if he 'a\always 'did the fingering it that means the hymen was long gone and no bleeding would occur. Virgin simply means a person who has not had sexual intercourse
