I fear that we are playing with fire on one hand and something reasonable on the other. If you suffer even a mild form of GID then psychologically you will actually do more harm then good trying to suppress your CDing. On the other hand, if you truly feel it is a fetish or something you have a mental handle on, then perhaps you can "take one for the team?" I wish you luck, but like PaulaQ and Kimdl93 have stated, its a two way street, and both have to work together because at least for me I don't see how this part of me is particularly selfish, and burying it may in fact end my life earlier then I wish it to end! (Through stress, depression, etc.)
