i will try to be brief, I have searched and searched already. My bum hurts. I have always had discomfort while riding but since I mostly rode trails I spent a decent time standing up. Back in July I got really into road riding and my discomfort level went up to about a 6 or so. I recently bought a 2nd hand road bike and my pain level is like 8 out of 10. I can't sit more than 5 minutes. I have tried 2 new pairs of shorts with different padding, a new selle Smp sadle, and my old sadle I was using when I was borrowing a friends road bike last year. I set my sadle height and fore and aft using the old methods we all know. I have tried different angles on the seat. Depending on the angle my pain is either frontal in the area between both private parts or if I tilt it back a lil to relieve that pain then my typical sit bones hurt. The only time I find any comfort is on the drop bars, and it has always been that way. I can't remember the last ride I did where I stopped cause my legs were spent. ALL MY rides end from bum pain. I almost have tears coming out my eyes at times. Soo friends does anybody have any advice. I don't think more shorts or sadles will fix it I'm afraid. Any advice would be amazing!, I would be forever grateful! Also how would you rate your bum pain 1 to 10?
Definitely, it's absolutely hideous to have to endure "8 out of 10" pain when riding. Our sport wouldn't be nearly what it is if everybody had the same issue. Even though I am a fitness trainer (thanks for the shout out, Fidodie), I can't say I have unique insights into saddles. But, I've struggled with some of the same issues over the years and have thought a lot about them, so here are a few ideas (other than the many other good ideas already suggested).
Bike saddle pain "generally" seems to fall into two categories for men (for women, it's often anterior pelvic pain due to their wider hip anatomy, which can sometimes be relieved by lowering the front of the saddle). The first is penile numbness, which results from compression of the pudendal nerves. Guys way back when used to try to tip their saddles downward to avoid the compression, sometimes resulting in their weight sliding forward down the saddle and overweighting of their hands (as you've noted). Enter the Selle SMP saddle and others with the cut-out or scooped-out mid-saddle to nose area. These seem to have had a good deal of success at relieving saddle problem #1 as the pudendal nerves are theoretically spared compression.
You haven't mentioned the numbness issue, though, and have mostly focused on the second common male saddle complaint: sit-bone sensitivity (if you search on the 'Net, you'll see references to the "ischial tuberosities"). I've found that these areas do seem to "toughen-up" over time and get less sensitive with frequent riding. You haven't found that to be the case for you, though. If I'm not mistaken, that 140mm width saddle is in the "average" range, i.e., there are saddles made both narrower and wider (I think Specialized makes 135mm and 155mm saddles?? Don't quote me on that, but the point is that they have wider and narrower models). I think I'd begin by seeing if one of these options helps provide some relief. If sliding down the nose of your current saddle seems to be an improvement (knowing that the saddle is narrower to the front), I might investigate a 135mm-ish saddle. Otherwise, go bigger and see what happens.
Hopefully, one of these different-width saddle will allow you to support your weight on your sit-bones in a way that doesn't cause pain. Beyond that, just trying different brands of saddles may help, but this can be frustrating as the process can appear never-ending (I know from personal experience). Since sit-bone sensitivity seems to be the issue, my guess is that the more thinly padded traditional saddles will not be the answer; yet many riders find that leather Brooks saddles (after properly broken-in), provide the ultimate in comfort for them -- and they have NO padding (but in "breaking-them in," they mold to your unique anatomy, broadening the contact area and reducing pinpoint pressure). During the "break-in" period, though, I'm told they're none too comfortable. I think the current models have a much shorter break-in period than the in the "old days," when it took close to a year of riding, in some cases, to get them to mold properly.
If all else fails, I recently saw a reference to a saddle (the "Infinity Seat") designed to provide support through the soft tissues of the butt, NOT the sit-bones. At this point, we'd have to still consider this an "unproven" design, but there are testimonials using prototypes which sing the benefits of what seems like a counter-intuitive approach. There are even some ultra-endurance cyclists expressing an interest in this saddle (for one, the third place finisher in the recent 2015 Ididarod Trail Invitational, that 350 mile race in Alaska). Financing for production of the Infinity Seat is still being raised through a Kickstarter campaign, so I don't think it's even available yet, but it appears to be "in production."

There's been a lot of great advice offered in this thread. I hope you can find a solution to the saddle pain soon as there's nothing that will improve your cycling experience more at this point!
