After our last conversation, I got to thinking. I can't imagine you going into a book store and buying an appropriately descriptive book on sex. I can, however, see you picking out some anatomy tomb with the pictured diagram of the reproductive organs and that's not going to help. You'll end up thinking of it as some scientific experiment and that's not what it's suppose to be like.
So, I went and picked up a couple for you. Don't be too worried, it really isn't as horrible as you think it is. Not when you're with a decent guy. I promise. Good luck.
