Hello, Thanks for posting on HCM, Your problem of not having sex properly is related to chronic masturbation. Due to the fact that you have been masturbating for several years, it had worked in your brain in such a way that makes your contact with a woman difficult. First of all you will need to get examined for urethral infection by getting a doctor to do a urethral swap and screening for STDs. If there is any infection, then it has to be treated. You will need to abstain from both sex and masturbation for a while. This will help rebuild your limbique system so you can adapt to having sex with a woman instead of a masturbation. You should try not to worry and know that you will get better as time passes. See a doctor if you do not get any better. Hope this helps
