Hi Sir, Welcome to Health Care Magic I can certainly understand your concern and worry about your size of the penis You have mentioned that your penis size is 5.5 inches, which is definitely an average length of the penis, so there is nothing to worry about that . It is definitely sufficient to satisfy your girl. i dont think there is any need to grow it more , there are some drugs with testosterone for its growth and some surgical procedures. but I advise it is not required in your case, more over surgery may lead to serious complications There is a possibility that because of overweight , fat can be deposited in the lower abdomen and around the pubis, which may make your penis to look smaller in size...as your weight is 95 kgs, which is definitely overweight for your age , try to reduce your weight by regular exercise and proper diet. I can suggest you to regulate your weight by regular exercise, fat free diet, avoid junk foods and food on the streets, have plenty of water around 6-8 litres per day, have fruits and green leafy vegetables. Post your further questions if any, I will available to take up your follow up questions Thank you
