Sorry about my english. It´s not my mother language so I there are some mistakes once a while. From what I could see, ya guys are more interested in teasing or stuff like than in change experiences. I´m sorry about that. I´m a member in some sites who have foruns like this and I´ve asked the same question in all of them. I´ve got some nice answers. I´m sorry I cannot say the same from here. I came to ask ya guys that since I know there are great guys here, but by the way, there are some "shits" also. Sorry about the bad word.
