This is just a fun mod I made for my male characters to have a laugh with - the idea is mainly for naughty screenshots. That and I just like randy men! Now includes cut and uncut tackle with and without Prince Albert piercings. There are 'normal' sized ones, and 'large' sized ones for larger-than-life men!
Find them in an Ayleid-style 'coffer o' boners' in the Testinghall - type COC TESTINGHALL to get there, then take the right-hand green-lit door to access an outdoor test area that can be fast travelled from.
These are made specifically for Robert's v5 male body, but some will work with v4 as well. Some may not texture up right, as v5 has extra mapping on the texture to support the cut versions of tackle.
These also come in useful with the many sex mods out there - females don't visually change, but males 'point' when excited! Boners! v5 (muscular)Boners! (slender patch)
