Sex is considered a vital part of life, just like eating, sleeping and breathing. Sex can make you feel good about yourself, and it can help you feel closer to your partner. But, sex can also be a destructive force. In fact, some people develop unhealthy preoccupations with sex, and over time, they may find that they’re unable to control their sex-related behaviours. These people may struggle with their illnesses, as they’re too embarrassed to talk about their thoughts or their urges.
