This is true. This forum can be confusing sometimes because many of you preach how you want a 'feminine, submissive' woman but then on the other hand, you expect her to be masculine, take the lead and chase.
@BeExcellent has written about this and imo you'd be wise to listen to her.
Yeah, the insecure ones who lack self esteem, self-respect and seek your validation and approval will reach out first after sex, it has very little to do with any genuine interest in you as a person and man.
It's about validation/approval, and unless you're seeking a quick hook up, such girl will become a huge PITA, chasing your arse and not allowing you a moment of space and peace. Classic Cluster B in many cases.
I agree with the Duke when you're vibing with a chick, it doesn't really matter who reaches out first, you're too busy vibing and f*cking to worry about it. It's about balance and common sense.
But generally, if you seek a feminine submissive woman, for gawd's sake give her the opportunity to behave like one and YOU take the masculine role and LEAD.
Waiting a couple of days is good practice. 5-9 is too long and frankly silly. Assuming you like her and care if you see her again. It reflects insecurity, weakness, a cry for reassurance and most savvy women know it's a game and will laugh at the silliness of it.
Leave the silly game playing strategies to woman and believe me they have plenty up their sleeve.
Act with confidence, strength, and purpose, assume she is interested (why wouldn't she be should be the attitude) and be MEN. Lead.
