There are many stories of women like Sati Savitri, Anasuya, Arundhati, etc. They are all Pativratas, this I heard from my childhood but I never heard of the names of any males.
Sri Sri Ravi Shankar: Why, Laksham, Ram, they were all Patnivrathas. Ram said, 'besides my wife Sita I am not going to look at anyone else', and that’s when the entire problem started. Surpanakha came to marry Lakshman but he refused. Had he married her the war at Lanka would have not taken place at all. It would have become the house of his in-laws. He said,' no, I am already married to Urmila and I will not marry once more'. Ramayan started because of this, because of Patnivrathas. In those days their father had three wives but Laksham refused and said,' no I already have a wife'. Ram also saw that his father had to compromise after marrying three times and he decided one is enough.
