You don't need NLP crap to do that.
And I have, when logistics have kept meeting up impossible SPAM.
But wouldn't you rather have your dick in her when she cums? But hey, to each their own.
Of coarse I want my dick in her!! And what better way to get it in her than making her cum without even touching her? I mean if some chick gave you a hardon and made you pants wet every time you heard her voice I'll bet that not only would you fuck her in a second but you would want to spend as much time with her as possible.
If you make a woman cum just with your voice she will begin to imagine what it would be like to actually fuck you. Her very small brain will say to itself "WOW! This guy already made me fire one into my panties just talking to him! What would it be like to actually fuck someone with this strange power?"
Also I am an extreme narcissist so it plays to my ego to have that power. Imagine the control you would have in any relationship? If you want her to get in the mood you make her cum. If she does what you want her to do you make her cum. If she won't run out in the rain to get you a 12 pack in the middle of the night you hold that gift back and refuse her as you roll over and go to sleep the same way a woman pouts when she doesn't get her way (the no blowjob for you punishment). And think of the possibilities of phone game or even phone sex.
This is a way for us to take back our power as men. Think about it. Women have a 100% monopoly on who gets sex, when, where, and how much they get. If she gets pregnant she gets to decide weather to have the baby or not and if she does decide to have it thats okay because the guy gets to pay for it. When there is a divorce they usually get the kids, the house and half your shit so I think being able to give her pleasure or withhold it is a fair trade and it will not only give you back the power it will make her treasure you like the prize you are since you have her ticket to heaven.
What if you find yourself in an argument with her and use that tonality and make her gush I'll bet that would take the fight out of her. It might be fun to fuck with her a little as well for instance make her get off at a nice restaurant or at a funeral. Maybe make her cum in front of her parents.
Imagine if you had a female boss at your job! Well I'll bet you would get that promotion rather quickly no matter how many more qualified people applied for the position. What if your at a business meeting and the other guy brings his wife and as you are talking you set a ticking time bomb in his wives skirt while it seems like all your doing is having a normal conversation and wouldn't it be doubly fun if he brought his daughter along as well?
Lesbians offer a whole world of possibilities as well. Talk about giving someone a sexual identity crisis? How much fun would it be talking to 80 year old women and watching how uncomfortable they get when in public they feel a sensation they haven't had in 25 years in front of everyone in the diner? Fucking hilarious!!
