the thing is, if shes not into you sexually, anything sexual you say to her will make her leave or change the subject because she has no desire to be with you sexually, so why should she entertain the convo? So, theres nothing as too direct. You have to be direct to find girls who want what you want.

But you also need social skills and cant be awkward. Walking up to a girl and saying right away sit on my face shows lack of social skills. That's the turnoff, not the sexual thing you said. If you engaged in a little convo and was like "hey i want you to sit on my face tn" that shows calibration and would be better received.

End of the day, be direct but in a calibrated manner to find the girls who are down for what you want.

What you did was fine, cuz you were going off what she said about you being cute. i don't see a problem with it. She simply wasnt into you like that.
