LOL @ all the people who live by a pre-defined "checklist" of rules.
It's not a matter of first date, tenth date, marriage or never. It's a matter of doing what one feels is right FOR THAT SITUATION and not being so closed minded because of a set of previously established universal rules. Whatever the chemistry dictates is ultimately what is "right". If the moment calls for a first date fuck, then so be it. If the moment calls for a few dates (days, weeks, months) then intimacy, then so be it. There is no right or wrong so long as the person does as the 'gods have laid forth'.
All these people who live through a set checklist and concrete mindset are fools. No sex until date #5 after having went on 3.5 dates racking up 17.5 hours worth of my time and spending $267.35 on me. Fool. Likewise, she's toast right away if she doesn't have sex with me on the very first date and give me what I want. Fool as well. Someone who goes with the moment and situation at hand (which varies from one person to another) is ultimately the wise one.
I have went out on dates where I waited a few days, weeks, and even months before having sex because it just felt "right". Likewise, I have went out on dates where I had sex on the very first date. Does this take away from my self-respect? Hell fuckin NO! I have my self-respect because I don't live by a narrow minded ridged way of thinking.
So please people, stop watching and living through Oprah, Dr. Phill and all those self-help relationship books.
