question: Hi doctor, I am 26 years old. I am going to get married soon. But I am worried about my small penis. The length is only 2-2.3 inch in flaccid state and about 3.7-4 inch in erect state. I would like to increase the width and length of my penis. Is there any medicine to increase the penis length without any side effect? In young age, I masturbate a lot. Is that the masturbation has affected the penis size? Will it affect my marriage life? Rather this, I am having nightfall problem. It occur minimum five times a month. Earlier, the occurrence was more than seven. I am suffering from premature ejaculation too. My sperm will come out within a minute of slight sexual stimulation. Please suggest me some medicine for premature ejaculation. I would like to get a permanent solution for nightfalls. One doctor suggested me to take some multivitamin like Methyltetrahydrofolate which can increase blood flow around genitals. It will act as antioxidants and can alleviate sexual performance as well. Is the medicine Methyltetrahydrofolate helpful?
