Once something is connected to sex and shame it becomes addicting. I'm pretty sure we all masturbated and felt shame with this, and like most addictions, it's the shame that keeps us coming back. If you don't feel the shame anymore, then it is still most likely connected to the pleasure part of the brain. I felt this was a choice of mine, and I'm recovering from it. I haven't dressed for a while, but there is part of me that still wants to. Coming here and reading posts seems to fulfill the need. Anyway, just my $.02.
