To the OP, it's a great idea. The biggest problem is, there are too many guys with small dicks and shallow egos for it to come to fruition. They'll review the shit out of providers all day, complaining about CBJs, mommy tummies, loose kitties, or how much they weigh over what's in the pictures. Oh, but let them be on the reviewing table. Go back and read a thread like this from days of old. It was chaos.
Guys want the freedom to be fat, ugly, lazy, soft dick fucks who's lack of youthful vigor be kept anonymous. Am I a hot, sexy stud with a perfectly sized yet slightly monstrous cock, all the hobby funds to spend, with never ending stamina, wearing out providers left and right? Not a chance. Probably won't make the top 50. But you know what, it's not that big a deal. However, if I knew I was being 'reviewed' in any way, I'd be inclined to take a little better care of myself, if for no other reason than to get better mileage out of hobbying in general. Should be doing that anyway, for longer healthier living. All of us. People don't give a shit about dying, until death is at the front door, going "What's up!", which by then it's too late.
The benefit of a 'male review' is that it would eliminate or minimize the need for references, I think. If you don't have any, you realize what a nightmare it is, trying to see ladies that require them. We all know not all ladies like to give them anyway. Kinda like pushing a cement ball up a hill. I saw mention of a guy review getting 'old' after 6 months. Really? Why? Providers go 6 months without a review, and it doesn't seem to affect them negatively in any way.
I think some ladies are just too lazy to write them. Once guys settled in and saw the benefits of them, they'd want more reviews, which again, requires work on the ladies' part. Writing them is a hassle, admittedly, and one has to be 'in the mood' to write them (this, ladies, is why there is sometimes a delay, or one not written at all. The mood never struck).
This would also make guys play nicer, knowing too many shitty reviews does them no favors. Oh, yeah. This is the big killer for guys saying NO to this, I think.
I'm nice to ladies, because that's just who I am. I don't have to force it. For some, being nice to 'hookers' (as some of you like to put it) is too much of a chore.
Then again, maybe I got it all wrong and reviews for guys would suck and would screw everything up. Well, why not try it and see. It's only a dumb idea if it doesn't work.
Guys could always implement a 'no review' policy, eh?
