I had the same thing happen when I lost mine.But I was raped & still never to this day have bleed for sex.I do know that yes there are different tissue types that don't split fully to release the blood. But it will cause you now problems for me it has been oh my 20 years ago. I was 11 when I was raped the first time but him. I am now 31 with 3 kids & been pregnant 4. the miscarriage was not related at all it was after my 2ND child. So you have no need to worry.
Many people don't bleed the first time they have sex. It is different for everyone.
Personally, I never bled during sex and I would go 6 months in between.
Nothing is wrong.
Some bleed don't bleed. There's nothing that says the first time you have sex that you have to. There's also the chance that you didn't lose your hymen when you had sex either. It could have broken before from any number of things including sports, using tampons, running.. etc.
Why would you want to know what kind of tissue your hymen is?
