#1 : As a man, you are dominant and assertive. Lead the conversations and tell stories. Make sure to ask the girl questions every once and a while and try to make her laugh. The stories can be of things that happen in your everyday life or things that happened to you as a kid or something of the like. Not just girls, but most people like a talkative person. The reason being they don't have to respond much. However, like I said, make sure you ask the girl some questions every once in a while. Dont just be a mindless ass robot.
#2 : Awkward moments are the killers of everything social. In my life I have always tried to be the one saying something when everything is quiet and always trying to keep everyones vibes up. If there is an awkward moment, it can make your friends bored of you or think you have run out of things to talk about. If there is an awkward moment, it can make people laugh at you or think you are weird. If there is an awkward moment, it can make a girl start to doubt how much she wants to hang out with you, because awkward moments are just awkward. You can get out of awkward moments by just changing the topic or asking questions or something of the like.
#3 : Do things. Im serious. Thats as simple as it is. Do stuff with the girl and try to work out a bit on your freetime or get a sport. Girls love to watch their guys play sports. Doing things can be as simple as watching a movie together or going out to dinner. Or it can be a whole ass vacation or going to a state fair. Whatever it is, the girl wants to do stuff, and if you can't entertain her, shes gonna leave you.
This is something everyone should keep at heart. Its one of the things I have kept at heart since the age of 10. I realized people needed people like this, and so I made myself this way. Im not a very emotional person and I dont like emotional people, but I have to at least try to hear about peoples days so that they feel like theyre enjoying life and people care about them.
