We all know that even if a woman conveys some form of interest in you it doesn't mean that she will want to sleep with you. I am pretty darn sure there is a missing component that most guys don't get escalating with females that will want to make them want to sleep with you. Women make it hell of a lot more difficult for men to sleep with them; despite what people say about females (even the ones that appear shy) and how they are more sexual then men, they still make it hard for guys to physically have sex with them. I have even realized it in party scenes too. No matter how drunk she is, she would turn down certain dudes. When I am interacting with a girl I am always myself, at my best and flirt--the conversation is never serious just her and I talking (of course I let her do a lot of the talking and avoid barging in) at times I would kiss close (not a lot) and it is at this point where I do not know how to effectively move further to the bedroom. Mind you I do not have a lot of sex in my life and I am 23, most dudes my age are slaying.
