1st Base - Is Kissing, french, open mouth or just a peck. Also any above the belt touching is included in this base

2nd Base - Hands below the belt. Fingering for girls or hand jobs for the guys.

3rd Base - When mouths are used below the belt. Essentially going down on a guy or girl. also This base includes the sex toys.

4th Base or Home base/plate - Going "all the way," doing the deed, Slamming it, Fucking, Sex, intercourse, "doin it," getting friskey so on and so forth.

(some people use a 5th base or a 'grand slam' to refer to anal sex while other include it in the 4th base. its really up to the individuals wheter they want to include it)
no example needed the sexual bases spelled out for you in the deffinition like a fricken manual

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!)
