Before we starting "playing" with chastity, I measured 5.9" when hard (I liked to call it 6" which is considered average by one major study ( http://wwwu.edu.uni-klu.ac.at/amiklaut/dr_nick/answer19.htm ). But that was years ago, and now we've gone through almost all the various chastity devices (including some inexpensive metal ones) -- with the type of device and duration of lock-up becoming more serious along our journey. We went through all the CB devices... Starting with the CB2000, which everyone knows broke every 6 months when the plastic welds let go and you'd have to order another. To the Curve, which for most "average" males leaves a lot of rattling-around room when soft (by then my wife had me pierced with a Prince Albert ring). To the CB3000, finally a plastic device that would tend to last a year or more before the seams let go. To the CB6000s when my wife liked the picture of it's compact size (we jumped right past the 6000 because I was starting to shrink -both soft and hard- by then). I'll be honest, we (she) were pretty pleased with the CB6000S -- it was tight, concealable under jeans. And my chastity turned into weeks and sometimes months with only an occassional release (but LOTS of teasing while tied up). So the "playing" had progressed into a regular game, and eventually into a true serious dom/sub relationship that including cuckolding. My size started to dwindle too. Today, it is barely 5.4" when really hard, and 5 1/4" when hard most of the time (we/she measured it just last night). So now, instead of being in the "average" range, I'm in the bottom 25% of size and my wife loves it more as it gets smaller. She says she's shooting for under 5" hard ! We've also moved from the plastic CB to a mature metal CB (Queen's Keep), and physical/emotional step has been a huge one for both of us. Instead of looking down and seeing something plastic that could easily be broken off if desired, it is clearly permanent. I can't describe the increase in submissiveness -- almost like now I can't wait to be locked-up, and forcibly kept in it forever. Our only complaint about the Queen's Keep is that it's more obtrusive than the CB6000s and shows under some jeans. So we just ordered a new mature metal Jail Bird which they said can be curved down more sharply. We've also shortened the cage length to only 2" because I often have a little space in the 2 1/4" Queens Keep when soft. And it seems my wife is very serious about getting my maximum length under 5" when hard. Will update our journey after we receive the Jail Bird, but I seriously doubt that I'll be out for more than "tease-time" until it arrives in ~6 weeks.
