My partner and I are in the market for a new penis. We currently use a "Spareparts Hardwear" harness with a "Vixskin Goodfella". Upon our search we've discovered the wide world of prosthetics and are very drawn to the realistic look and feel of them. That being said it seems many of the high end models are made for the FTM community whom glue the prosthetic to themselves and urinate through them. We would like to solely wear ours in the Spareparts harness without it having a void or hole for urination. We are having the hardest time finding a triple-density constantly erect penis with a squishy back end that will set into our harness properly.

Initially we were drawn to the "Real Cock 2", but it is very large and their customer service wasn't helpful at all in answering questions.

We'd like it to always be erect, so no need for the rod that bends down for "packing". We'd also like the thin pliable outer "skin" that moves freely for optimal sensation. We'd like the shaft to slide through the o-ring section of the harness and have a wide back of silicone to fill-in the harness pocket a bit... so the one wearing it could have full vaginal pressure. Do you know of companies that offer these options? Essentially we'd like it as real as possible, price is of no concern 😀.

Thank you all ever so much for your help!

I heard freetom has a few prosthetic that are good for penetrations.
There's also this site called transthetics and they release new products every now and then and they update their older prosthetic.
They're currently working on a new prosthetic that allows penetrative sex without a harness and it's called "the hot rod"
You could also fill it with water or other liquids and ejaculate. Seems like a good prosthetic and I might buy it once it's out if it's not too pricey.
Here's the link and description

It's coming soon so it'd keep an eye out for it.

Thank you for the response. I'm currently looking at Emisil Erect 02. It meets all the requirements, except they cannot tell me if wearing it in our SpareParts Hardware harness will cause damage to the area where the shaft meets the testicles. Our current Vixskin is splitting at that pint and fear the Emisil will do the same.... probably more so a matter of riding it slower to limit stress at that compression o-ring point. Just want to be thorough seeing as it is a big investment.
