The We-Vibe Tango is known to be used for clitoral stimulation by most which is really its main purpose. The Tango is NOT safe to be inserted into the anus but you could easily insert it into the vagina. Tango isn't your everyday bullet vibe by any means this is a bullet on steroids, an will blow your average bullet out of the water with the power it packs!
If you have dildos that have holes in the bottom for a bullet to be inserted to make your dildo vibrate, Tango usually can be inserted into those holes. If you have any trouble getting the Tango into the bullet hole add a small bit of lube an it should slide right in.
Tango can be used by those who are male and female bodied. For the gentlemen you can place the Tango underneath his testicles while giving him a blowjob to make it more exciting. You can also cup the Tango in your hand while giving your man a hand job. For the ladies you can insert the Tango if you wish but I would avoid it if I were you, just a personal advisory. Ladies can use the Tango on their clit for clitoral stimulation or insert into them dildos that come with puny little bullets that barely vibrate. Together you and your partner can both experience the vibrations of Tango in many different positions, if I use the Tango on my clit while my partner is penetrating me he too can feel the amazing vibrations.
