Hi there I'm Stephan, saying hello from Greece. A while ago I picked up the hobby of making my own dildos. It's something I can't do very often because materials are very expensive. I don't have any equipment like vacuum pumps, only my hands and had to trial and error my way around different problems and made plenty of dumb mistakes along the way which ended up ruining my projects, but eventually I managed to make some good dildos. They're made from platinum silicone and I've tested these and they're all delightful in my experience. Images of my best ones attached.
