You just don't get it do you? There are no answers for you here. The answers are found in you and her. If she hasn't responded to you, she isn't interested in you any further. She doesn't owe you any explanation.
The way you have denigrated women (as a whole) in your posting history here, amongst other things, I don't know why you feel so bad that she made out with you as eagerly as you say you did.
If I had to take a guess based on just what you posted here, I would say you are the reason why there are no more dates. Your own words here shed light on your heart.
You said she mentioned being exited enough to possibly have sex and you said you were ok with it if she wanted to. She saw right through your hormonal reply.
If you were wanting to grow into a relationship with this girl, you don't do it by doing and saying what you did. She may have been testing you to see if you would show your true intentions, which you did. You grow into a relationship over time, much like how an oak tree develops deep broad roots to help withstand the varying toils of the conditions around it.
Time to mature, treat women with the respect they deserve, speak and act honestly with others, and maybe one day you will be capable of having a real meaningful, long-lasting relationship that is built on something besides pretentious behavior, vanity, and hormonal centeredness.
Sex is not the basis for a meaningful relationship. Anyone can have sex.
