That's a common myth and misunderstanding by males ...
Blood means that the man is doing something wrong during sex and is hurting the woman or that the girl/child simply is too young to have sex with a man. Most virgin adult women usually do not bleed during "consensual" first sex if they are well lubricated and relaxed. And in current modern times most women probably have used fingers or toys before first sex.
Note :
It's not like that the hymen would seal a woman until broken since how could a woman have her period (monthly bleeding) if she is sealed ?
"During puberty, estrogen causes the hymen to change in appearance and become very elastic." (wiki)
Characters in legal games are 18+ years old so there should be no virgin blood unless the woman has the rare case of an abnormal hymen and then her gynecologist would probably fix it before first sex.
Best talk to your gynecologist for more details ...
Look I have not slept with a ton of virgins, but I think you are not correct.
Obviously if a girl uses toys, such as dildos, that is the same size as a penis, then yes, you are correct. her hymen will probably not be intact anymore.

Not so. A hymen is not sealed, but the hole is very small. Too small for a penis, but big enough for a finger.
Fingering will not break her hymen, unless she puts in multiple fingers.
Also, no amount of lubrication and relaxation will keep a hymen intact. It's not a muscle that you can relax.
A penis is simply too big, and if you still have an intact hymen, it will 100% bleed when you have sex the first time.
My partner masturbated with small objects and her fingers for years until we had sex the first time and she bled for sure.
If what you are saying is correct, then most young woman will pretty much will still have their hymens intact, since it only stretches when you have sex.... I call BS
TLDR; Does a virgin always bleed on the first time? No, other activities including (but not limited to) horse-riding, masturbation with larger size objects etc. could cause the hymen to not be intact anymore. Does a woman that still have her hymen intact bleed the first time she has sex? Of course.
