Dear sir, I am having problem as above. I am newly married and facing the problem as above, then I discussed with one pharmacist and take medicine from him, I did not consult with Doctor, The pharmacist given two medicine 1. CAVITRA-50 and the other one is 2. REVITAL. After taken this medicine I have no problem to do the relationship, I have used the medicine continues one month and have a satisfied sex with my better half. one day I had a trial without medicine, That day I have a satisfied sex, but the other day again i am facing the same problem, insufficient hardness of penis.Then after I have continued the medicine again and having sex with my life partner. My fear is, What is the problem for me to do sex without any medicine? Is the medicine is give any side effects? Is the medicine is acceptable to use regularly? How can I solve my problem?
