It is safe sex: you don’t have to be afraid you’ll get a STD. But that doesn’t mean there are no risks involved. It can have a (very) negative influence on your life.
Some people who start experimenting with cybersex get addicted. They spend hours every day and are not able to control this habit: it becomes compulsory.
When you are in a relationship and you tell your partner about the adventures on internet or your partner finds out, it may be felt as a real-life affair. Your partner may feel betrayed, hurt and /or angry.
When you get used to the short and exciting sexual encounters of internet real-life contacts may seem more difficult. On internet contacts are casual: you leave when you don’t enjoy it anymore. But real intimacy often takes time and hard work.
When you spend a lot of time on cybersex you may become isolated, not going out and meeting (new) people. It may stand in the way of getting on with your life.
