What does the Quran’s description of Jannah influence men to do?

The Quran’s description of Jannah influences men to do good in order to be sent to heaven. Islam teaches men should contain themselves and act sexually moral in their life, so the quote, "and beautiful-eyed maidens like hidden pearls’ a reward for what they used to do” suggests heaven is a place where men have permission to fulfil sexual relations with women, which would encourage them to do good to be set free from constraints during human life.
