My hormones were raging so I dated a girl that I new was very active sexually.  I think I tried to stick in her belly button but was not figuring it out at all.
She was awesome, she said let me show you how this works.  She sat across from me, spread her legs and explained where the clit was, how it was great to stimulate, lick and suck on that as well as where to find the pussy from their.  She was a nasty girl but one hell of a lot of fun and an amazing sex partner.
What I miss most about those days is being able to nut 2-3 times in a row and two or three sessions a day.
