New Belt Chastity

I got my brand new Belt Chastity Belt today… I had to put it together and hope I did correctly. It arrived without instructions (Deep sigh).. How tight should it be? Also the rubber peels off around the edges even after putting it on.. What is the best method for keeping the rubber attached at the sides? Can’t wait to take pictures of the new belt worn by me… Another question… I love Belt Chastity Belts and I adore Full Corsets… Has anyone discovered the optimal way to wear both together.. yes, a cage would be simpler but I prefer the belt over the cage… Rivkah

It's wise to mention which type or model of belt you have, so someone with a similar one can give advice...
