What are the kind of thing at home that can be made into a sex toy use to masturbate myself. I love to make or use one.

Go to hardware store and find black foam pipe insulation. Various sizes. Some brands are very smooth and some are not. Try to find the smooth ones. Cut to the length of your boner and take the sticky tacky stuff off. Then duck tape to hold it round. I use a handlotion in mine.
If you want pics pm me.
