Yes, I have. You should try it! There is no way you can get splinters. They are sanded down and varnished. I only have one wooden dildo, and I like it a lot. Hope that helps.
Wooden dildos are wonderful . I have several, and I've never had a problem with them cracking or splintering - they are sealed or formulated well. That was a worry I had before I got my first one, but I've never worried about it since.
I would not worry about splinters. I assume they have a hard outer coating for the finish. That would protect them from cracking and getting splinters. We have never used one. I have one on our wish list. In the mean time we will use our glass and silicone toys.
