JanesW I could really submit myself into the lifestyle. (we are saving for the mortgage so we want to be more cautious before investing on a western-custom made belt).
I think is wise.
JanesW 1.There are two kinds of waist belts: the "belt" or the "wire". It's obviously that the wire one would be more light-weighted, but less enduring. I'm also worried the wire may hurt waist, compared with the belt. Would there be anyone who have experience with the two different kind of waist structure?
I have a FS belt, but I have wire only in the crotch structure. A wire in the hip or in the waist, probably will hurt you. When you wear a wire structure belt you have to wear it very tight in comparison with a normal belt, and in fact a standard chastity belt is very tight, so, the wire will dig in your flesh.
JanesW 2.About hygiene. Currently I work from home so I could even use the showerhead every time after pee. However if I need to go out and use the toilet outside, would a water spray and toilet paper could clean it?
Yes. It does the work. However, when you are outside, you should think that thigh bands will difficult the access to your shield.
JanesW 3.For the rear belt, there are either "two wires" linking from the secondary shield to waist band at back, or an anus ring allowing for toilet use. Will the metal anal ring cause much uncomfortable when sitting?
No, I have it, however with all the belts you should be careful with sitting in hard surfaces.
JanesW Second, after wearing thigh band, will it become impossible to wear any trousers?
No with the bands.
JanesW Also, where should I measure the perimeter of my thigh? 1/3 of 1/4 from above? Or just by convenience?
It depends. In general I recommend wear them mostly high, due the most low, the most restrictive they are with same chain length.
JanesW a lot of cheating/fighting the belt activities could be estimated...and luckily I work from home and just need to go out for groceries
Bands make it impossible, however, do not try to wear them 24/7.
