which packers pass the "grope test"? (or stps)

sup guys i'm in search of a prosthetic that feels like a natal peen through underwear, rather than kinda collapsing on itself/just feeling obviously like silicone lol. so ideally also with 3d balls /realistic sized ones?

i would LOVE to find an STP that 'passes the test' too but my hopes aren't high there since it kinda does have to be hollow to actually function; they tend to all flatten a lot ime but maybe there's something out there that's what i'm looking for, idk.

this may be a silly question but i've been going to parties lately and been too nervous to make out with guys cuz yknow what if he starts touching me and notices💔that would majorly suck haha. thanks!
