2nd base is touching yer boobs

Agreed.  Second base is touching above the waist, third base is touching below the waist, and third base is all the way, as the kids say.

Agree with Thea.  Second base is above the waist, below the shoulders.  Third base is any genital contact that is not intercourse.

No, no, no! Oral is a level up from petting but not as high as penis-in-vag.  it has to be third.  and boob touching might as well go to first base, as far as i'm concerned

It's difficult for me to say.  I'm a bi female, and since I started my sexual career primarily lesbian, any non-clothed genital contact that results in sustained intimacy (possible orgasm) seems to me a home run.  Hand jobs that are more than just a brush, and all oral.  Even with guys.  Sorry.  

Wait, I hate baseball.  Goaaaaaaaaaaallllllllll!!!!!!!!

I was taught by my first g-friend it was that the bases were the 4 "f"s...

1. French

2. Feel

3. Finger

4. Fuck

Where I grew up:

First base was kissing

Second base was contact with breasts

Third base was contact below the waist

Home was sex

But what about getting called out at the plate?

My boyfriend calls making out that can turn into sex "rounding the bases."

I'd agree that 3rd is genital contact that isn't sex and that home is, of course, sex itself.

I'm going with the majority here:  

1 - kissing

2 - petting/boobs

3 - genital contact (this includes oral)

4 - intercourse

Weird how there are variations on that ... I wonder if it's a regional thing?

oral doesn't have a base.  Sorry, Emily.  If you need a base for oral, it's gotta be third.

middle west checks in - agrees with

1. kissing

2. boobs

3. non-sex sex

4. intercourse

Okay...back when I was young and dinosaurs roamed the Earth...

First base was deep kissing and over-the-clothes petting.

Second base was under-the-clothes petting and clothed kisses to naughty bits.

Third base was bare skin contact and serious sexual touching short of intercourse [basically mutual masturbation, usually not to orgasm].  Hand jobs where the participants remained clothed were a grey area.

Home plate was any deliberate penetrative sex [oral or vaginal] that resulted in orgasm, esp. for the guy.  [Back when dinosaurs walked the Earth, the female orgasm from anything but serious bedded, probably matrimonial sex was essentially a fantasy].

Conversationally, forget about "the bases", and just describe what happened. Or are we still in junior high being adolescents??

The bases are definitely the four "F's"

I had a base system as complicated as the dewey decimal system growing up, but the basics are what most people are saying:

1st is kissing

2nd is above the waist

3rd is below the waist

4th is intercourse.

My friends & I then added sub-bases to each one... I think oral was 3.3, but sadly I have no record of the details. I shoulda written this shit down, but I'm sure if I had, my mother would have found it...

This might be generational. Since I'm a Gen X'er:

1. Kissing

2. Boobs

3. Genital (non-intercourse)

Homerun: Intercourse.

God knows those Gen Y kids probably put blow jobs at a foul ball.

1st base is meet irl.

2nd base is FaceBook Official.

3rd base is sex including oral and possibly several other people.

4th base is having it posted on the internet for all to see.

Come on, everybody knows this!  Are you guys just pretending?  It's ignorance like this that causes teenage loneliness and ostracism. Fight ignorance today by updating your myspace profile.

First I need to state for the record that the term "finger banging" makes me wretch.  When I was a wee lass the base system was oddly complicated.

1st base: kissing

2nd base: boob fondling

sloppy 2nd: mouth to boob contact

3rd: manual genital contact

sloppy 3rd: oral

home run: intercourse.
