Here is a question in response to yours.
Why is it that we act out soooooo privately and secretly? Even on this forum many of us hide behind usernames. I did too for a long time. When I first started posting on GYE a few years I enjoyed the secrecy and hiding on GYE too. Basically anything to do with sex was mine and i did not want to share it.
The answer to me is that I identified so strongly with lust, it made me feel good, it validated me, it soothed me, it took away my fears, it gave me an escape from dealing with life ............
Now when the "me" who acted out, meets the other "me" who strongly identifies with learning Torah, da'avening and avodas HaShem, an internal conflict begins. (To deal with that I often just acted out again!)
Yes, I care about speaking lashan hora, Shabbo and everything else, but i don't lock myself in a room to do these avairos!
