When you are in the Safari ap, you should see a curvy arrow in the upper left (near the URL bar). Press on it and you'll get a pop-up. One of the options in that pop-up is to forward the link via e-mail. Press it and your e-mail will pop-up for you to fill out the TO: field and add a message if you wish. Then, you hit Send and that's it.
Hope this helps.
