Hi. Thank you for reaching out to Health Care Magic. I do not understand what you mean by artificial sex but in case you mean masturbation, then it is alright to do it. Some people may suffer from the following when masturbating - Rash Itching Injury Weight loss and weakness This can be because of the loss of nutrients in the semen or from the physical injuries received from masturbating. Here are a few things that may be useful for this. Avoid masturbating too often till there is injury Use a good lubrication method to prevent injury Take a diet rich in fruits and green leafy vegetables Get lots of rest Sleep more than 8 hours a day I hope this helps. Please reach out to me if you have any other questions. Dr Vignan
