Hi Murthy, Welcome to HealthcareMagic Forum.
You haven't mentioned what do you mean by Sex Addiction in your Case? Do you Masturbate? Do you watch Porn? If Yes, it is absolutely normal. Kindly don't worry and it wont have any adverse effect on your Future sexual life. You are 33, Why don't you consider getting Married? If you Masturbate, do it only when you are sexually aroused may be twice or thrice a week. It wont cause any harm to your Body.
If you Smoke and Drink, QUIT. Eat healthy nutritious balanced diet which should include fresh fruits and Green leafy vegetables. Avoid stress
and Exercise regularly. Practice relaxation techniques
. This will help you concentrate on things which are more important in your Life. You are unnecessarily getting stressed out.
