there are many ways to gratify yourself sexually besides vaginal intercourse and you will not have to worry about impregnating her.
Also you will have hours of fun exploring all these options and they are all free!!!!! Well, a few things require a visit to your local adult book store for tools and supplies, but it's a one time expense with care and maintenance, just keep plenty of lubricant and batteries around.
Please keep us posted as we are all interested in helping the young people :wink:
