Good clubs are those that are well-lit! Ok, here are my tips on grinding:
1. Grow long hair.
2. If you don't have long hair then go for an extremely short cut. Preferably showing scalp.
3. A guy who is big doesn't have to care about the length of his hair!
4. A thin guy will find it difficult to get hot girls!
5. Asian chicks rarely dance with any guy out of their race
6. Bright colors are attractive. Black with red stripes is the best I've seen.
7. Go late. Once the dance floor has picked up you can go and choose what you want.
8. It is best to go upto a girl who hasn't noticed you in the club yet. Just go grind her.
9. Don't stand there and look at girls dance too long. They will reject you when you approach them later. If they notice you staring at them then you are out.
10. Belts can sometimes be bad. It can poke the girls.
11. Dark shirts are attractive. Graphic shirts may not be.
12. Kiss them on the neck whenever you want. You will notice all the girls look at you later. The girl will just grind you differently. Don't let her get too horny if her friends are still in front of you.
13. If a guy just goes for her back, it is the right time for you to go for the front. Just as soon as another guy does it.
14. If she calls me sometimes I just shake my head like no and then pull her later. Insane compliance.
15. Girls with less make up or ugly girls dance with bad guys. Their friends let her dance with guys who are thin, medium sized hair whatever.
16. Sometimes I just cut through the entire crowd and a new ass shows up! Be careful not to look like you are walking round and round.
17. I have manicured nails. They just pull my hands all the way to the front. It makes me clumsy at the back.
18. Don't get drunk
19. Don't breathe too much on her neck.
20. If you are out with a friend then she will dance with you even if you are one of those skinny guys.
21. Interracial girl coding is not as strong as it is among the same race. So if different races are dancing go for them.
22. If they are just standing there then go poke the most beautiful girl with you finger and offer her your hand. She will dance with you.
23. If another girl is into you, that is if you have social proof then the hottest girls will dance with you no matter what you look like.
24. If your pupils dilate they WILL choose you. When I stare blankly not knowing what I am seeing my pupils dilate.
25. If the DJ plays the right songs they will grind insane. Some songs just dont get it.
26. If a girl is dancing alone or is dancing behind a guy then go for her because she won't get girl-coded.
27. If a lot of people are dancing in a line, then join the end. If there is a gap anywhere in the line jump into it. They are all facing the same direction so you won't get girl coded.
28. Colognes are a strict no-no. They will just wave their hands like it is hot in the club.
29. Sometimes a chain around the neck is attractive. This adds more bulk to your upper body. It is an illusion. The chain should preferentially be right around the neck unless it is not your type.
30. If she is pushing her ass out then it means she is ready. You have to be quick because guys are always eager to please them.
31. If the girl is dancing too close to her friend then she doesn't want to dance with guys just yet.
32. If a girl in a group says no then save approaching that group any time later. That group has blown you out. Nobody will dance with you.
33. If you lose contact with the girl then establish contact once again because she might not be interested if your physical contact with her stops.
34.* Pheromones. Girls are attracted to the pheromones that are produced in male sweat glands.
35.* Accessorise. Goggles etc.
36.* Full sleeves inside. Short sleeves outside.
37.* A pink shirt
38.* Color contacts
*Must be field-tested before confirmation
I think the real key could be increasing free testosterone levels.
