Yes and an uncomfortable experience it was too.
You need to attach your dildo to some kind of stand and back on to it.
The advantages are that you won't have to put up with an yap or emotional stuff from a partner and that you are less likely to get a disease.

You can buy dildos that have a suction cap at the base - you can stick it to tiles, shower wall, washing machine, neighbors garage door when your tweaking at 3am then you remember they have a security camera 8( :D.
Use lube - silicon based lasts longer than the water based ones dry out and can become sticky.
