Me too! I used to never have to use a mat when doing floor exercises at my gym. Now I need one or my tailbone hurts!
Gah, maybe my butt's just weird, but my tailbone hurts despite having a mat! I hate floor exercises for this reason -- it's always been like that, even at my heaviest.
I've got the granny panties (which I think are cool to see LOL) and the jeans things. I used to hate to wash jeans because I didn't want to get into those tight things for a day (they do loosen), but now I am so happy it doesn't matter! The other thing is I've had to change pillows again. First I am like a freak when it comes to pillows, I have seven I use, but now I have to line them differently. And it's not the bed, it's only 2 years old.
