Same with the wetStuff, I was worried about getting a reaction from it (Strange I know but I don't normally use it and have never ever used a toy like this before) but so far so good and it actually felt really good when just using my hand to lube my self and felt even better when using the STU.
Only thing was drying it after cleaning, I used my small box fan which dried it quite well but took a little bit to dry the inside properly but all in all very simple cleaning/drying needed.
I am actually looking forward to using it again tonight, lucky my mum went out with my sister this morning and wont be back for a few more hours yet so had time to give it ago when it arrived and will be using it again tonight, this time though I might try it without heating see how different it is.
Now I just need to pick a place to stash it and the lube for next use so no one will see it
I am really pleased with it and glad I did purchase it there were so many times I was gonna back out or even get my order canceled after paying for it but I'm glad I didn't.
