SEX what is sex why does it feel so good. A lot of people who have sex especially boys they go around saying the girl was wack or this and that. There is no such thing as a girl who is wack or a boy who is wack about having sex. What is sex I ask . Sex I a connection that u make beyond get close to someone the reason when u have sex with someone and it don't feel good then u don't love that person. Because if ur heart is not connected with that person then so will the bottom. It's like a multiple outlet plug if the main source is not connected then how the rest of it going to function. The more ur heart connect with somebody the better the feeling.
