I basically don't like wearing thongs, unless I have a good reason to do so (e.g. seducing my husband).
Then, I'll wear them for a day or evening, just to get us going on a hot night. But overall, I find them terribly uncomfortable, and I much prefer bikini-style underwear that doesn't irritate my butt crack. I also wear them if I am wearing tight-fitting pants that would otherwise show a panty-line, but I try to avoid those...
However, I do like anal sex. It took me a while to learn to relax enough to enjoy it, but now we have anal sex once every couple of months to spice things up. It's best when I've had half a bottle of wine or so... and a vibrator to help out on the front side. Good times.
