When I was a teenager in the 80's it was all about boys wanting to 'finger' you.
And by 'finger' I mean shove their finger in and wiggle it around randomly 
I remember no clitoris action, no one tried to get me to suck their cock, no one was shagging in my huge group under 16.
It was just the snogging (lots), tit feels, and the finger. Along with a bit of frottage.
