I often wonder how people have sex. Mentally, how? Not physically how. As a poor person myself, I cannot bring myself to engage in sexual activity with any man. After searching online things like why do poor people have sex or why do poor people have so many kids, it said that poor people have sex because it’s comforting. I can’t see how sex is used as a comforting mechanism for the poor. As a poor person, the way that I feel from poverty, I just can’t bring myself to have sex for “comfort”. How does sex make you feel good if you are poor?
