Am I a Douchebag and playboy?

Hey everyone. I tried to read the rules and this situation is kind of hard to pinpoint in a specific topic, so hopefully I did not break any rules.

Just a bit of backstory.
I watched this video about nofap.

I wanted to nofap for about a month, and usually I do not masturbate that much, because I concentrate on work and socializing more. I am a confident person. Not afraid of talking to other people etc. But wanted to start nofap to actually improve myself in terms of trying to it out. See what improvements I get. But also to use that "fapping time" to actually work.

I started nofap and it were great. Although it made me into a playboy, and only looking for sex and not relationships.
This lead to my trying to go out with my female friends, and then my animal instincts kicked in. Like in the video describing that we need "reward" I felt I wanted to do it. Although I did not like her on a girlfriend level, but just wanted to have sex.
I felt terrible. Making me into a creepy dude who just wants sex.

I did not do it because I did not wanted to hurt her feelings, but I could see her lady signals like playing with her hair, legs etc.
So I need some help here.
How do I break down to her that I am looking for sex without ruining our friendship?
Do I just ask her? And how do I go about it?

TLDR: Got on nofap, now I go out with girls more, but only for sex... being a creepy playboy. Almost did it with my friend.

 

I see... Thanks for answering. I really appriciate it.
It is kind of sad, but I guess that is the way then.
But even if it is not a bad thing, then how do you go about that problem?
I mean we live in a world where almost all women might find it creepy that a guy only wants to be with girls for sex only.
Or else I have to actually learn to control my desires. Which might be the next step.
But how do we go about that? A stronger desire than sex might be hard to find.
