When she lets a straight male friend do her hinge voice prompts and he does something like compliment her ass or her tits. She's clearly got a straight male friend in her life that wants to fuck her.

If she's a slut, she'll know it's normal for guys to nut super quickly on occasion. It happens to everyone bro, and it's most likely because you're putting too much pressure on yourself to perform. She probs appreciates the fact that you went down on her more than the fact you didn't last long because once you get more comfortable with her she'll get good head and dick game. Next time, try not to think about not cumming, enjoy the sex and maybe use those creams/oils that numb your dick and make you last longer

If she’s already sent you nudes, you could say something like “how about I take you on a date and you can try something even juicier than a steak”

Or if that’s too much you could say something like “on our date I’ll give you more to remember than just the food”

Scrap the pedophile prompt. Could get taken the wrong way

Sounds like she's got some trauma or PTSD from a past experience. I don't think you did anything wrong but sometimes if girls have had a traumatic sexual experience in the past like r*pe, anything sexual, even if its harmless and consensual, can trigger things in their brain that tells them to stop at random times. I know cos my ex had it. My advice is that if you really like her you could probs try again but incidents like this will probs happen again.
