Hello , I understand your concern. I am Dr. Arun Tank, infectious disease specialist, answering your concern. Yes, cialis contains the tadalafil. This drug improve the blood circulation to the particular point. In erectile dysfunction it improves to the penis. It only helps in the erection. But it has no relation to the orgasm. Orgasm is controlled at the brain level. After a certain age like 60 orgasm is going to start reduce. So you can achieve only with your will power. I suggest you that you can watch the porn movies, read the article related to sex before you want orgasm. This will help you improve the orgasm. Cialis will give you erection. So with this both the thing you can achieve good erection.
