I would love to discard the pelvic floor theory, if there was a reason to do so and I don’t think “C’mon guys” is an adequate reason… If you look around the internets, there are plenty of guys who don’t even know what PE is who have exactly the same firm flaccid symptoms. Not to mention the fact that conscious relaxation of the pelvic floor area, for me at least, immediately relieves the firm flaccid, which literally normalises before your eyes, when the relaxation is done properly. The problem I feel is that that state of relaxation should be normal, not something that needs to be consiously forced, therein being the problem.
The deflated glans issue I now consider a separate issue, and one where I agree pelvic floor tension is not the cause, however, I do think the pelvic floor stuff can alter the symptoms of the deflated glans, thus all the confusion.
