STP problem (help?)

[CatBat]

I have a RM prosthetic (flaccid, use as a packer) but I hate sitting to piss. It makes me feel terrible.
How might I go about using an STP while there is a prosthetic attached to me?

I'm going to assume using a urinal is out of the question but a stall would be a good start.

Thanks....

You have it glued to you? I'd say maybe the old medicine spoon could do the trick if you can master it.

I would sell the packer on one of the FTM garage sale groups and put the money towards a 3-in-1.

The best 3 in 1 STP prosthetic I have found is through a company called Peecock. Google it.
