Oddly enough, the advice I think is most useful doesn’t directly relate to sex. Trina notes that if you are trying to heighten your desire you might first need to address other personal and relationship issues. I think this is great to remember. As much as you try, it is really hard to separate life stresses and leave them at the bedroom door.
However, once you work on or, hopefully, work all the way through problems, you’ll find sex all the more awesome.
