Honestly i'm not sure how to help you, however I will leave a few ideas because i do know how this can be frustrating.
Out of all he posted...this is all that holds true.
Heres what you do....
First girls won't want to do anything unless they are really really wet.
What I would do personally, make out with her. Pull her hair, bite her neck. Do all the sexual techniques from David shades 'Give women multiple screaming orgasms' book.
Once she is wet, after about 5 minutes of all those things (pulling hair, bitting, rubbing your hands up and down her body) get in her ear and bite her ear. Then whisper "Baby your so wet right now huh?"
IF SHE SAYS NO.
Shes a fucking liar. Slap the bitch and tell her don't ever fucking lie to you again....
don't do that....but let me tell you, girls get wet just as much as we get hard. FACT.
Anyway, so once you say that, she can respond in any way. If shes like "how did you know?" "oh yeah I am" "your turning me on stop it" (which means fuck me) then be like "I want to make you wetter baby"
Take your hand, pull her hair. Then Slide your other hand down her pants (ass part, like litterally in her pants, past her asshole and you'll have to reach over to get her pussy. Feel it.)
She is less likely to reject it if you go from behind. FACT
Then finger her for a bit. Shove one in.
FIRST TIME I DID THIS I WAS FINGERING HER ASSHOLE. fact.
Don't do that. It will be realllllyyyyy wet. Trust me.
Finger her until shes moaning a bit.
Take your other hand thats not soaked in pussy juice and WHILE MAKING OUT. Un button her pants. If she moves your hand, take hers and put it above her...like this
Took like forever to find that. But just like that. you know. Where she can't move your hand.
Then stop pinning her hands and unbutton her pants. Once unbuttoned, just take your other hand out of her pussy and pull them AND the underwear off.
your choice here: Take off her bra (easy for her to stop you, blah blah we shouldn't do this, I wanna wait.
A girl's boobs are very sensitive and very sexual. So when that shit comes off, it means business.
Or just push her on the bed and start to finger her while making out/eat her out.
There you go. I could write pages on eating out/fingering/sex. The rest is up to you.
