Is it bad idea to try flirting this way?

I'll always be at parties and make girls laugh, girl will come over to talk to me and the whole night we'll be joking around. But, nothing ever happens between us (I blame my self not making a bolder move and the 'new me' hasn't got a chance to try yet, being away from home).

So I'm at a party or just hanging out and everything seems to be going well, I can pick body signals that seems like she is interested, we are laughing, she makes eye contact, and may touch every now and then.

I see videos of these pick up artists online and they start using sex related pick up lines, even on girls they are meeting for the first time and it SEEMS to work.
I guess it depends on the girl and the situation but would I be blowing all my luck if once I feel we are getting somewhere I try some sex related line/joke.

For example we are playing some sort of game and I say 'If I win I get to have sex with you, if I lose you get to have sex with me' (I think I saw this one online and the girls laughed at it, I'm not sure, its just a quick example)

Meh...I would not use those lines. They are just cheap and stupid. Just be yourself. They are already laughing with you and finding you interesting, so just go for more and get a number and/or ask them out.

The thing about pick up artists is they dont show every girl they aproach in those videos. Not all girls are so welcoming. Also they done it 100 of times and became numb to fear. The best pick up artists dont use ready sentences but just are natural feel the girl and go with the emotional wave.

Theres also diferent kind of girls and diferent scenes. Like day/ night, street/nighclub etc. So everything matters. Just dont create some kind of character that girls will like but be yourself. Otherwise hiding behind the mask is same as banging yourself with a hammer. Girl will become atracted to that mask not you.
