Do you really wanna risk being the guy who shows up at the emergency room with his dong in a vacuum? If so, then hey, knock yourself out, make sure you tell the vauum how purty it is =).
is it possible to use a normal vacuum for masturbation? i ask because i saw it in a few hentai vids and manga and i wondered it it would actually work and be able to be used to get off.
oh its gonna get worse before it gets better DO IT!!!
If you can clover the hose with your hand and its fine I would guess it wold be ok to use your penis. But I can't really see how that could get you off. But what do I know.
