'Create an exact rubber replica of your penis!' The Make Your Own Dildo kit from Empire Labs promises a quick, fun and easy way to make your own dildo from a cast of your own (or lover's) cock.

The kit contains everything you need to immortalise your dick, including moulding powder, liquid rubber and liquid skin, a two-part moulding container, thermometer, stirring stick and bucket, plus illustrated directions. It all looks a bit intimidating and very messy – and it is.

The method is really precise – the moulding powder is mixed with water of an exact temperature, stirred for one minute, poured into the moulding tube and left for two and a half minutes, during which time the 'model' for the cast – that’ll be you - needs to get an erection. We’re sure Strictly Broadband can help you with that, if your computer is within view.

Then you stick your cock and balls into the moulding tube, which needs to be held in place for around a minute while the gel sets. For anyone thinking "what if I don't fit in the tube" – unless you're hung like Sledgehammer, you won't have a problem, trust us. The mould is then filled with the liquid rubber/skin and left to set for 24 hours.

The process can easily be carried out by one person but having a second person to help with timing and stirring helps (and with getting the required stiffy), making this a great kit for couples to use. The kit is reusable and extra bags of moulding powder and liquid rubber can be bought separately.

The results from the kit are quite staggeringly detailed – it really does give a precise rubber replica. The extent of the possibilities only become clear once you have the dildo in your hands… It gives a whole new meaning to the phrase 'go f*ck yourself'.

Be warned your girlfriend may well demand you suck your own cock to see what jaw-ache she suffers (or worse, if she lets you do her up the arse). But then in return you can ask her to let you DP her with your own cocks…
