This happened to me a couple of times before I figured this out. You meet a girl for the first date, say Wednesday just to put a time frame on this, you have a blast, mid-date you are snogging and groping somewhere in a park. Then you drive her home, make out in your car for half an hour then you let her go home. As she does, she turns to look at you with those doe eyes every few steps. You text her something cocky/funny/sexual/somewhat sweet, she replies immediately, after a coupe back and forth you back off to keep the tension for a day or so, then text her Friday noon with one of many openers and... She doesn't respond. She responds good 5 hours later and just "not herself the way you got to know her" anymore. You keep time differential, blast her balls, then it's Friday night and you don't respond over the party part of the weekend. You text her closer to Sunday night with some short "OMG" DHV story, or a picture that suggests that you had a helluva weekend. She is lead for a while, but you feel coldness. She texts you that she will call you on Monday and she never does. So what happened? Here is what - you got her so horny on Wednesday night she came home and masturbated screaming out your name. She went to bed craving your cock. The next, or one of the following nights she went out with the girls to keep you out of her head, meets a lesser guy but bangs him anyway because of the horny state you put her in. Now he is in and you are out. Therefore, I cannot stress it hard enough, gentlemen, always calibrate for an f-close. If a girl lets your hand under her skirt, she will let you finger her. If she lets you finger her, she will let you fuck her and it is your responsibility to overcome the LMR and make her get off. Regardless where the making out session becomes heavy, near her place, your place, buddy's place or a goddamn park, escalate and fuck.

The reasoning is roundabout but its there. If you are getting hot and heavy you must get them into bed, or at least force them to give you a red light.

I'd ask, why are you turning a girl on if the intention is not to fuck soon? Would you like it if a girl did that to you? No! In fact, you'd be pissed off! I certainly would be.

There is also the other part of why to fuck them, it's awesome fun. Yeah, crazy thought right?

Thats not normally how it goes down. The reason a near fuck normally results in a MIA is that the girl is later out of her emotional sexual state, and realizes she almost fucked some smooth operator she barely knows, she is also aware if she sees you again you will be fucking her. This usually causes enough stress and turmoil to scare most girls off.

However I agree with your premise and conclusion

Detox is right, a big reason you have to is that if you don't she has time to think about it outside her emotional state. The anti-slut shield goes nuts and she think "fuck that was close."

If you DO fuck her she will want to see you again so that she doesn't feel like a slutty one night stand.

Female post rationalisation is fun.

Haha, the answer to "why not??" is rather simple - I was a total dumbass. I'm glad I learned on my mistakes though as opposed to repeating them over and over in an endless cycle of frustration.

Combined answer to Detox and Mattr. It makes sense what you say and is very possibly the likely reason. Yet, I have observed (a rather frustrating experience) on more than just one occasion that the girls would ended up jumping a dude they would have just met a night or two later, much to the surprise of their girlfriends, who would later describe her behaviour as "completely uncharacteristic". Perhaps both points apply to some extent.
But regardless, I highly appreciate your comments and thank you for confirming my premise.

... Brings up a thought though. Although doesn't apply to any of the girls that I have formerly lost in this manner, it's just been too long, I wonder if reignition is possible. Say, wait a month or so the text an SMS opener, say a "who is this?" or "just saw a cutest fish, reminded me of you" Or would you say that "Oh, that was close!" emotion that she tags you with is somewhat perm? Did anybody try?

I agree, its worth a try. Ive done this before and it has worked, but usually it doesn't.

I reread your message and now I'm inclined to say, you're spot on, at least in my particular case. I'm a Norwegian and am "blessed" with a typicall swimmer physique - 6'3", massive chest and shoulders, rather too noticable. I learnt to compensate with a happy-go-lucky personality, indifferent demeanor and humour but regardless of the years in the field I still sense this "OMG, this beast is gonna tear me apart" vibe with most of my dates, which early in the game was essentially the reason for near fuck fiascos. It's a natural intimidation factor and yeah, compensating with personality is all I can do about it. I think you are spot on because once the personality is withdrawn from the frame, the image remains that can be perceived as a danger. Again, thanks for your comment mate!
