The Slippery Slope

Okay, this is kind of gross, but I have crotch problems. Nobody, but nobody, wants to hear about this, so here goes.
Patterns of fat deposition after the age of 50 and my genetic truckload of pear-shaped inevitability make all my extra blobs collect below my waist. First this meant that my callipygian form pouffed out in back, a bustle of extra flesh. Deep ass crack became deep ass crevice became deep ass crevasse. Now I can not keep that flesh apart for enough time in the day and night, naked or clothed, so the flesh is not let to dry and that leads to chafing and itchy red splotches. Yuck, right?
Next, in my efforts to deal with this moisture problem, I began the habit of ass-spreading. Sit down, separate ass cheeks. Stand up, press knees together to separate ass cheeks. It seems to work most of the time except when it's hot or when it doesn't. Not enough to bother a doctor with, and besides, what would a doctor say? Try this cream. Lose weight. Get normal. Be a man. Suck it up, cupcake.
Yeah, so. In fighting this running battle--which is what we are all doing on this side of 50, at the top of the slippery slope, hoping to hold on for a little while longer before the accident or catastrophe befalls us that makes it not a running battle any longer, but a last ditch defense until the death--I am holding my hoo-hoo closed up tight like a sphincter and the ass crack wins while the hoo-hoo loses. A warm moist closed environment that is no longer being flushed out periodically by my periods. That's right. Two months gap now. Of course, my first thought was: yeast infection. So I went to the drug store, bought the suppositories (what an ugly word for a yucky thing) and used the hermetically sealed plunger deal to stick a little bullet up my vajayjay. And then slowly it softened and melted out and stained my underwear even though I put a pantyliner on and then it didn't even help. So what is it?
I looked online (mayoclinic.com) and found out it might be sexually transmitted (no.), or bacterial (maybe), or atrophic vaginitis or some non-infectious source of irritation like scented pads or douches or sprays or creams (no.). So maybe it's just the poorly aired plastic bag of a middle-aged woman's coochie that has some low level bacterial thing going on--or we have to consider atrophy. It's old and dry and thin and fragile and subject to opportunistic infections, but what can be done about that? Is it time for estrogen rings and HRT patches? So soon?
And here I thought that finally being freed from the seemingly endless round of menstruation would be a liberation. More like one step forward, three steps back. Get ready for the anxious scanning of the slippery slope for handholds, little scruffy bushes to cling on to.
