I believe it's about finding solace and comfort in, "the rhythm of a strangers skin." She knows better yet continues to do it, even after she is caught. ("Friends and family looking in to my only hiding place") I'm sure there is the alcohol abuse in there somewhere too. But there is definately a connection she feels with these men she has sex with and it's what keeps her alive. Or at least, that's my interpretation of it.
