Need female to female jack

I bought this: https://smile.amazon.com/gp/product/B00IFHMSIM/ref=oh_aui_detailpage_o01_s02?ie=UTF8&psc=1 to go with my Empi TENS unit. Sadly, both items are boys. Now I love watching gay sex. It's hot. But it doesn't work for electronics. I have been searching the internets all day for a 2mm to 2.5m double female jack with no luck. I've checked Radio Shack and Best Buy online, nothing. Anyone able to help me out? I realllly want to play with my new toy!

If you know anyone with a soldering iron you can make your own with parts from any electronic co,

2mm to 2.5m double female jack

I'm not sure I understand what this is. Do you mean two female "jacks" back-to-back, one for a 2mm plug and other for a 2.5mm plug?

Try this we bought one from Amazon...there are 6 left for less than $30. https://www.amazon.com/Allbright-Health-Exercise-Adapter-Include/dp/B01LBRMJTU/ref=sr_1_1_s_it?s=hpc&ie=UTF8&qid=1477944213&sr=1-1&keywords=pelvic%2Bfloor%2Btens%2Bunit&th=1

My TENS unit is a male, as is my Nocturna Vibe. I need a female to female jack to connect the two. Thankfully, hubby can solder, so he's working on a solution.
