BASE number

To start off, BASE jumping is an acronyme for Building Antenae (uninhabited tower) Span (bridge or arch) Earth. It is very similar to sky diving, however the is no plane. If you are to complete a BASE jump off of at least one of each of the four different genres covered in the acronyme BASE, you can apply for a BASE number. They are awarded sequentially starting with BASE-1 to the thousands.
The first BASE number was awarded to Phil Smith as BASE-1 in 1981.

Sexual Bases

1st Base - Kissing, open mouth. Also any above the belt touching is included in this base.

2nd Base - Hands below the belt.

3rd Base - When mouths are used below the belt. This base also includes the sex toys.

Home Plate, (Home Run) - Intercourse

5th base or 'The Dugout' - Anal Sex.

A grand slam, would be achieving all of these on a first date.
First, Second, and Third are the typical sexual bases. Anything beyond those and you probably aren't using baseball metaphors any longer anyways!

(Unless of course referring to 'The Dugout', because that's just hilarious!)

1st base

1st base is of course what everybody start's out with ..... It's just pretty much "Making out" Now making out is very passionite and everybody reading this I know enjoy's it (Unless you havn't gotton to 1st base yet but there is nothing wrong with that it's harder for some people to work up the courage to even ask somebody out) Now making out you want to start out slow nothing extremely serious so wait about 2 minute's to start getting really into it so when you really start getting into put some pressure on it push against each other's lips harder not to hard but hard enough to know that there is somebody there and now that you start doing that you might start to want more so maybe open your mouth a little bit (don't tounge yet) Open your mouth and actually feel them breathe dot that for a while and now that you have done that now it's time to start frenching (useing tounge) Move you tounge into there mouth not too far yet maybe too when you start feeling there teeth (But if you do this and they don't return the favor stop and wait till she/he is ready for that) But if they are then when you move your tounge out and move it back in go farther and the more you go just go farther not to choke them with your tounge but just let them know that you want it and you know as this progress's it will get more passionite and then you will have to wait and see what happen's ;) Oh and before I forget when you start to tounge you may have some saliva from both of you but just live thru it, it doesn't matter it's actually some what enjoyable
