Our emotions affect our sexual functioning. It sounds obvious when you say it, but many people behave as if they don't realize this. Before, during and after sex, don't ignore how you feel just because you think it's unromantic or inconvenient. Talk with your partner about feelings you have about sex, your body or your relationship. If you consistently feel bad about sex or your relationships, consider therapy.
Sexual response is a reflex.
This message travels to the brain, which sends a message down the spinal cord to various parts of the body, instructing them to respond with tingling, extra blood flow, etc. Emotions are electrical and chemical events in the body. They either facilitate or disrupt the sex-related messages going up and down the spinal column. But if your partner calls you the wrong name, your emotions disrupt the sexual response. This is how common feelings such as anger, anxiety, sadness and frustration interfere with reflexes such as erection, lubrication and orgasm.
