Catholic men ...if you struggle with chastity and purity...I would highly recommend you implore St Joseph and St Paul with a small prayer of your own every time you are tempted or fall into sin. St Joseph because of obvious reasons and St Paul because when he speaks of a "thorn in my flesh"...I can imagine it was his natural urge for women. At any rate...when I find my mind wandering or tempted by the flesh...I find a small prayer to St Joseph and St Paul does the trick. Maybe St Paul has a special place in his heart for those with a "thorn in my flesh". Peace...out.
