Sensual Pleasures and their removal (MN 19 & MN 75) According to these suttas, is itsomewhat possible through seeing the inherent harm in sensual pleasures, to shy away from them? I remember that it by first experiencing piti during meditation that one slowly but surely starts to abandon sensual pleasures.
There is a sutta where the Buddha says that until he experienced piti during meditation; his mind was still capable of returning to thoughts of sensual pleasure. 

This said, starting the path requires abandoning sensual pleasures before experiencing piti. The Buddha abandoned sensual pleasures well before his development of the 1st jhana. 

The mind that never thinks of sensual pleasures is a non-returner yet the eightfold path for mere stream-enterers has the abandoning of sensual pleasures as its 2nd and 6th factor. 

Believing the 1st jhana must be attained before abandoning sensual pleasures is wrong view.
