Ho Xoved,
Having read your story here, I've got a feeling that your only problem is not having the right value that would back up your positive belief in yourself as a sexually free man.
If you're still a little bit confused about what I'm talking about here, just stay with me, and I'll make sure that you totally understand what I mean.
Everything you say and do to women is based on what you believe. Let me explain on your example.
You said that you hooked up with 3 girls who are something like your friends with benefits. What this is telling me is that you most likely believe on your subconscious level something like this: 'There's no fucking way that any one of this girls would like to have sex with me because they simply wouldn't want to have sex with me at all.'
By the way, by having the above kind of belief, you're your worst enemy in dating because having this type of negative belief will make you miss so many other opportunities to score women out there.
Here's another important thing about believing in yourself as a sexually free man.
In your example, that girl most likely showed an interest in you for two main reasons:
1) you have a great personality and you're also a good looking guy
2) your current belief kind of made her chase you without you even properly realizing because your negative belief about having no chance of ending up having sex with her kind of projected your non-neediness toward her.
The outcome:
she wildly wants you!!
The problem:
you don't want her wildly. Why? Because your negative belief is strongly holding you back.
The long-term problem: you're most likely going to miss many sex opportunities with women who're initially interested in you. Why? Either you'll kill these women's attraction to you or they'll instantly lose their interest in you as soon as they look at your body language and pick up on your negative emotions coming out of your body language.
And, you know where your negative emotions are coming from?
They're coming from your negative beliefs that are nested in your subconscious mind.
And, here's the truth on why your body language is such a big deal to women and why women easily get turned off by your negative emotions or they get attracted to your positive emotions:
Your beliefs control your emotions, and your emotions control your body language.
If you want to learn more on how you should go about fixing your belief, I suggest that you check out the first chapter on my blog's page about the subject on confidence with women at:

Hope this stuff helps you.
Let me know the results of having your new belief later. I'll be happy to hear your success story.
