I've considered buying an onahole.

I don't have any strong feelings on them. Since I live with my mum, it's not really an option to get one. If I were to get one though, I'd get either one of those small, chip-looking vibrating things, that you put on your penis with a little strap or I'd get a normal onahole. I think I prefer the first one, simply because it's small, cheap and handy. Also you don't have to clean it and it looks pleasurable.
