I truly think that frame of mind and the subconscious does have an effect also, My cucky isnt in 24/7 chasity but for over 8 years now I have relyed on lovers for my satisfaction, and my cuckys measurements have certainly decreased, he loves being belittled in the trouser dept and he has now also come to terms that he is a crap lover, after measuring him he has shrunk well over a 1.5" down to 4.2" and shrivels to next to nothing when limp, bless him, lol it seems the more he shrinks the more BBC i get! the perfect partnership for me!!
