Never been able to understand how anyone could bear to wear thong-type pants. I've always just thought -surely they must ride up and get into - the bit you don't want interfered with by your clothing??? Never understood it.
Anyhow, I sent for some M&S pants. Look like normal pants. Nice soft fabric. Comfy. Put them on, head out for the day. And -- oh dear, turns out they have a mystifyingly narrow gusset with the consequences I would think were entirely predictable. Not comfy after all! Much hitching down required 
And there wasn't even a warning!!!
Just - why?
Have I got a weird-shaped fanny? Is it unusually lacking in firmness? Is it in the wrong place?? How does anyone wear these things??
