Now I'm sorry to be having to do this, but since you're too proud to talk to me privately, I have to put this here and hope you'll see it. I hope it can be useful to you (And Bella)
As a Doctor, it is my obligation to educate the youth of Forks on sex education. Please remember Edward, this is the 21st century and everyone's doing it. You don't have to be the odd man out all the time. Beside's, Bella has been extra whiney lately. If you don't do something soon she may look elsewhere. And I know, I know, the first video says beastiality is ok, but it's not. Ever. Don't send her to such desperations that she commits this crime.
I would like to add, that the above video is somewhat misleading and outdated in the fact that: Masturabtion isn't a bad thing. Infact, it is quite natural to get handy with yourself. It may help ease tensions somewhat if you don't want to go full way. Take a paddle, if you're not going to swin, so-to-speak.
And this video may also help you learn something too. There's honestly nothing wrong with sex before marriage, son.
Now I've pulled a few strings at the hospital and got you a place on their 'Teens & Sex' course, there's a place for Bella too if she wishes to take it.
I've also spoken to Emmett and he has offered to give you as much advice as you need. Out of everyone he's most likely experienced in more areas than myself.
So that's all I have to say. I hope this was helpful to you.
Don't thank me, it was all in a day work. :D
