Yes I would do the same thing with the purple. The glass purple equivalent is much easier, and you feel it less and you can use silicone lubricant which doesn’t dry up as easily as the water based lubricant. I would recommend for sleeping, it is easier. I still have to try doing chores. I also noticed that if you sit up with it, it doesn’t hurt like the other ones did.
Are you at the beginning of your dilation process? I too felt like it was very expensive but i must say that it was worth it. It is good to have options.
