I have the same issues when I do a long or hot ride. I just deal with it... I have never mentioned it here, but I think you guys need to go a little easy on the OP. The Body Glide and some of the other usual tricks mostly work for me, but I get the burning after a ride still, at times. I actually went for my annual exam once, after I had been cycling a couple of years, and my gyn. told me I had "lesions," which she knew weren't cancerous or anything, but it looked very raw. I knew right away it was from my saddle, so I switched to a Terry Falcon. That helped a lot... but I still have the burning issue after rides sometimes. I've been professionally fit, and have tried all of the usual lubes. I am fine if I don't pee during a ride (not usually possible!) and I make sure I don't touch myself when showering after a long hot ride, because at times, any pressure will make me go through the roof.
It's the combination of sweat and some pressure, as well as having "ample" bits.
I did try a Brooks saddle for 6 months and it was an instrument of torture for me. I hated it. And, I don't have the patience to keep looking for the "perfect" saddle. Mine is good, I have it on all 3 bikes and the problem is much better. But... I have to say that not everyone is so super concerned regarding taking otc meds. If it works for the OP, then it's good.
When I was on my tour in Spain, it was so hot that I had the worst issues ever! I learned that I can't wear the Terry Bella shorts in really hot weather and that my Shebeest S Pros are really good for that. But, you guys would most likely be horrified to know what I used to keep the problem from totally ruining my trip; basically a combination of Body Glide, a lube the tour dour director got me, and Neosporin. That and a box of Baby Wipes worked.
