Rather than getting a PA piercing for this, couldn't I just tie the retrieval lines onto a threaded bead? . . . one large enough to prevent being pulled into my urethra?
And one more question . . . is the 1.7mm trimmer line fishing line? Available at sports dept of Wal-Mart? Couldn't you just extend the trimmer line in the same fashion as the retrieval lines so that you'd create a removable balloon plug? Let me know your thoughts. Thanks!
