I don't disagree. Honestly, I haven't had sex in over a year...and this isn't the first time I've gone this long. Doesn't have anything to do with someone not calling me back after though...but sex means more to me than physical pleasure and I enjoy it when it's with someone I am comfortable with/care about/know well. I just know myself and what works for me. I'm sure guys I've gone out on dates with think I'm playing hard to get though...but if a person wants to get to know you, they will, whether you give it up or not (and even if you do give it up, if the dude's still interested, he'll stick around...I've seen it happen with people...girl sleeps with guy on the first date...they end up dating, in a relationship for years etc). There really are no rules when it comes to love/relationships...it's so case-by-case...so you just gotta do what's is good for you at the end of the day.
Well not everyone has that mindframe, many women try to use their vagina as a powerful tool to draw man in and string them along as long as they can before offering it up. As someone who hasn't had sex in nearly 3 years those old tricks that used to work on me don't anymore.
The main thing for most guys is to conquer the vagina if they don't its a failure, and why they won't waste their time.
And , i've never seen that happen, whenever in my past life when I slept with a girl early on, my thoughts of her changed to she does this with every guy she's dating or chilling with, won't get serious with.
