If you are reading this, and fit the situation, then the subject is
already a consideration on your mind.

You may have read something on the subject, spoken to a girlfriend who
has passed through the experience recently, and heard about it in
school. We hope to help you here, with a short guide. It is for you.

First of all, you must feel it is the correct thing to do. You must
NOT be pressured into it, or the experience will fail to bring you the
pleasure and good memories you expect and deserve. You are in charge
of your life and body. You must really feel ready for it.

If you have been masturbating, you probably had clitoral orgasm, so
you know what is possible in terms of feelings. You must also, know
your own anatomy.

You know you have some outer lips that cover the vulva, and some inner
lips which are very flexible. If your hymen is intact, you are also
going to tear that, with the accompanying sensations and bleeding.
Find out.

In the second consideration, do not have sex if you have over-drunk
alcohol. You can become drunk and lose a great deal of your judgment
after even one drink.

The third consideration is INSISTING on the use of a condom with your
partner. The reasons for this are well known, and certainly there is
no excuse for not using it. You must be protected. This is a health
concern, a very good way to prevent conception, and generally a good
idea as it will help to slow down your partner by desensitizing him a
bit.

So to begin.
