I found out that by putting words between *'s they end up being bold, which wasn't my intention.
For moans, gasps, sighs, groans etc. I'm now using -'s. I think it looks better that way, since I generally don't like using bold text. I think it's more clear now, but let me know if you liked the previous formatting style better. :-)
Only chapter 6 and 7 were affected, so hopefully it won't bother too many people.
