Whilst prayer for forgiveness is good and honourable, one shouldn’t run the risk of relying on it a ‘get out of jail free’ card.
If you are suffering from a particular addiction to something - be it porn or anything else - you should also make materiel changes in your routines so that you don’t place yourself in situations where it’s easy to indulge your habit.
For example, if you are liable to indulge in your habit at bedtime and you use the computer for that purpose, move it from your bedroom. Do it now. Put it in the living room or the attic or somewhere else that’s not conducive to the activity, like in front of a window where, even with the curtains closed, your silhouette would give the game away to any passers by, since it’s my understanding that people with addictions don’t really want to advertise them to strangers, and who would really want to be caught masturbating by the little old lady passing by in the street with her shopping? (If you did, then you’ve got bigger problems)
Empty your sleeping area of temptation. That means posters of depicting scantily clad persons (or worse). It means placing within plain and clear sight pictures of, for example, the Sacred Heart of Our Lord.
As for star-jumps… I don’t think that’s a good idea: you’re just getting the blood and the adrenalin flowing and that’s probably exacerbating the problem. Better to have a freezing cold shower. That will, quite literally, cool your ardour.
Obtain for yourself a book of Morning, Evening and Nighttime Prayer and cultivate a habit of kneeling by the side of your bed each night and saying the Night Prayer for the day. It’s not excessively long and always ends as follows:
*Lord, let us be so united with your only Son that we become worthy to rise with him into new life, who lives and reigns for ever and ever, Amen.
May the almighty Lord grant us a quiet night and a perfect end.*
And then climb into bed and switch out the light.
With those words as the last thing on your mind before you go to bed, it should help you with a firm purpose of amendment, and you’ll be able to comfort yourself with the knowledge that you are participating more fully in the life and the Prayer of the Church. It’ll strengthen your resolve and weaken your addiction.
