Hi Doctor,I am Ramesh, 24 years old. My penis size is 2 inches and goes up to 4 inches in erection. I am very unhappy about it. While having sex with my girlfriend(2 of them), both of them pointed that it was very small. I am down with very low confidence and I am not even able to penetrate my 2nd girl friend. I don't know if this is due to my lack of confidence or due to my penis size. But I am seriously unhappy. I have gone through many articles in internet which says that penis size cannot be enlarged and some say that they can be enlarged. Please let me know if it can be enlarged and if you are the right person for it. I will be really grateful if you can help me out. Expecting your reply.Regards,Ramesh
