How far can you go in showing attraction to the girl in order to make her interested in you? Where is the line?

Personally, going a little over board is better than understating attraction. I will tell a girl she is hot, start to hold her hand or touch or body and say she is so hot I can't handle myself. I find that building it up big leaves no doubt in her mind and then either get the hookup or leave. Even leaving like a boss after the huge buildup leaves her wondering why a guy so into her dipped with no extended effort. He must get tons of women , huh?

True, but it looks to me that you make her feel too important this way. I always try to be the important one when I talk to a girl by using negs or DHV. With your way she has the power to choose if stay with you or not, while i want the opposite. I like to be chased

Aiming to be chased if you are looking for a one night stand is stupid. If you want to build a relationship, then fine. Who has time in one night to build that connection? I get in, let her know I want her with hardcore signs and then continue doing me. I feel her vibe, then I am in.

Not always true. It takes longer for sure, but it works for one night stands as well, believe me.
I still think that by doing things in a hardcore way you risk more to be shut down than by coming and give her a little after a little... Of course, your way is much better if you don't want to waste time.

It is mainly because I do not give a fuck. Try to take it as non-conceded as possible if you can, but I have been told I am very good looking by so many girls and that is why they are timid to converse with me or think I would be interested in them. Little did I know that if I just became the natural whore that I am and put myself out there hardcore, it eased them into the situation and it was candy.

Maybe that's why they need you to make them DHV.

Relationship wise, sure. But that is me. If I chat them up a small bit, a compliment here and there and just straight to touching, it is a go.
