I am a student pursuing my Masters in Business Adminstration. I married my girl friend of 4 years, when I was 23. Post marriage, I had difficulty in having an erection and also maintaining it during the sexual act after marriage. We were living together before marriage and I did not have any problem whatsoever. I was very depressed and started having sleepless nights. A friend recommended Dr. Karthik and we visited him. After a thorough evaluation with lab tests and scans, Dr. Karthik diagnosed my problem to be due to anxiety and stress. We had sex therapy for 3 weeks and now we are back on track and rocking. Since then, I have recommended Dr. Karthik to many of my friends and acquaintances who needed help.
