Fresh blood from dry humping naked

It could be from damage to your vulva, or particularly your hymen. Have you looked to see what it could be?

No not yet. But is the blood from the hymen fresh red? I feel like fresh blood is always from wounds or am I wrong?

But blood from the hymen would be because the hymen has suffered a wound. The membrane would have been torn. It has a blood supply just like many other parts of your body do.

Same blood as when the hymen tears when u lose ur virginity?

Yes. Hymens vary in thickness. A thicker hymen is likely to have a richer blood supply than a thinner one.
When a woman loses her virginity (the first time a penis enters your vagina), often her hymen is torn because the penis is much larger than the hymens opening. This is what would cause the bleeding associated with loss of virginity. However that may not always be the case for a number of reasons. Here are some:

The hymen can be torn, particularly if thin, through rigorous activity or through medical examination. Sometimes it can happen through tampon insertion or masturbation. If the hymen is thought of a 'virginity', then that can be considered as 'losing virginity'. That is a cultural issue rather than a technical one.

The hymen can be partially ruptured, with or without bleeding, and at a subsequent there can be a greater rupturing.

The hymen may be tough and elastic enough to allow penile penetration (particularly if the penis is a thinner one), and so no rupturing takes place first time.

The bleeding that take place is similar to any other cut or tear to other parts of the body.

I hope this helps a bit more. If you want more detail on any aspect, please ask. Perhaps you could indicate your particular aspect. I will try and help further.
