Hanky panky is actually a great idea. Semen has something in it that naturally softens your cervix. And it is absolutely the most fun you can have trying to go into labor sooner!
Kira pointed out walking. That's great too.
Other than that, there's not much you can do until the little one is ready. If this is your first pregnancy, it could take longer.
I also want to point out, not to rush it. I got majorly impatient towards the end. My ob wanted me induced after I went two weeks past my due date. I was induced, but it turned out they had my dates wrong, and took her early. She was most likely between 36-37 weeks gestation when I was induced.
So, take your time and finish baking that baby!
