What is the story of suvarchala and Hanuman?

According to Ramayan, when Hanuman was going towards Lanka, he takes the support of a hill in the middle of the sea. At that time, the body of Hanuman was so big that the hill was of the size of his hand. He places his hand on it and rests their for few seconds while the remaining body is still in air.

It is said that one fish (Suvarchala) swallows his sweat and becomes pregnant. It falls in love with him at first sight. She gives birth to a son called Mathsya Vallab. That is how Hanuman has a wife and son though he was virgin.

Hanuman is the greatest virgin the world can ever see.
