Another way of doing it, which is suggest in the article is asking what she likes on bed. This will make her feel special when you discuss this with her, and give you an excuse or chance to tell her what you like. This makes her more willingly to do exactly what you want, isn't that nice? You will like this guy, watch porn in front of her. Why? So you can let her know that the girl in porn do something that makes you hard, she may learn the same thing to make your penis hard as well.

Do you like pole dance? Personally I have no special interest but I am interest to watch pretty girls wearing so sexy to dance on the pole. And the best thing when she is doing this pole dance, she can burn the calories and stay fit. I think pole dance is cheaper and more effective that those slimming treatment in those beauty centre, right? It will be a good investment when you see her dancing in front of you. There is another way of telling her that she is fat, purposely buy shirt that she can't fit then she will feel that she's fat. If she receive your message, she will take care her body and you won't piss her off.
