Too many beta chumps fall into the trap of blurting out every fact about themselves on first dates with girls.
This feels tempting to the beta who's been told to Just Be Yourself by his female family and friends his whole life. It destroys any sexual tension that was once there. All the mystery has gone.
Girls don't want to hear you recite the Encyclopædia Betannica. It destroys all mystery and imagination. A girl's imagination is your most powerful friend, because it feeds their competition anxiety, which we often call Dread.
Nothing wets the female's loins like the mystery of the non-needy man who ignores her texts for days at a time, only to return with panty-wetting excitement and fun in spades.
The mere act of approaching her with boldness and clear (yet not overt) sexual intent will be enough to let her imagination run wild. By not giving her all of your attention, and by not overtly explaining your sexual situation at any one time, she will imagine the competition she has all by herself.
If a girl's imagination is your most powerful friend, then in turn her feelings of competition anxiety are your most powerful tool, and best of all, it's a passive process. By not divulging everything about your life story, combined with genuine non-needy behaviour, it'll happen by itself.
Take your time when describing your life. She needs to earn it. You should have a good enough lifestyle that any woman should feel lucky to be a part of it. If you don't, go Monk Mode for a few months until you do.
Casually drop in that you went on a date yesterday. If she asks how it went, just say 'yeah it was alright' and leave it there. She now realises that you're a man other women want to go on dates with, and hence fuck. See the power in that small disclosure?
Remember, when you approach her, you have already beaten 99% of the terrified beta chumps out there. She starts off with the assumption that you're an alpha. She's rooting for you, hoping you're the cool guy rather than the awkward one who fumbles over himself buying her a drink with nervous laughter.
Each self-deprecating story, each bit of nervous laughter, each factoid you give her about your past sexual history, chips away at your perceived alpha cred.
That last item is of prime importance. You can never benefit from telling her your sexual history. When I started out in earnest approaching girls, I had been with one girl my whole life. Every single new girl assumed I had had a bigger body of experience with girls than I actually had. This assumption is partly from their feminine solipsism, but it's mostly assumed because of your boldness and attractiveness.
Quoting a recent comment of mine:
The problem is that most dudes have the Monogamy-as-goal mindset, borne out of a desperate scarcity of female intimacy. Think we can all empathise with that.
For example when a girl finally replies to them on POF, they clutch onto her for dear life, acting nice so as to not offend her sensibilities, while at the same time she has 10 others. If they actually meet up, he'll splurge every fact about himself, destroying all the mystery. Women want to have 'figured you out' with their feminine intuition, not heard the Encyclopaedia Betannica. If the relationship does progress, it's in her frame, because she's the one who cares the least, and in turn has the most power.
'Spinning plates' or just having multiple female prospects, not giving all your attention to any one of them, puts the situation firmly in your frame, because your non-neediness will show through your choice of options. Also, your behaviour will indicate this choice of options, stoking her competition anxiety, which is your most powerful friend of all in dating women.
Once again do not conflate this with the concept of vulnerability. That's the principle of risking rejection through brutal honesty and qualifying statements, not crying about your spirit crystal.
Be vague, don't vomit every fact about yourself, and whatever you do, never fully tell her your sexual history. Nothing is more satisfying to a woman than the thought that she's "figured you out" with her feminine intuition. Burn the Encyclopædia Betannica.
TL;DR: Beware the trap of blurting out every fact about yourself. Your life is a precious commodity that women would be lucky to be a part of. Stoke her imagination and competition anxiety, they'll passively do more for you than any funny line will.
