Hi, at the very first time I did sex with my boyfirend it didn't bleed for me? Why is that? Is that mean my hyman was not there? Or it broken that time without bleeding? Is it rare case ? Is there any way of checking it now?

It is possible that your hymen was already broken. Using tampons, for one, can cause a hymen to break. There are also other injuries that we can suffer when we are younger that may cause this too.

The only accurate way to check it would be to go to the doctor for an exam.
