I'd like to keep this PG-13. I am interested what the fantasy of other CD's would be.
Do you desire to have both boy and girl parts? I'm going to circumvent the obvious contingent answers by presenting 2 scenarios:
Scenario #1
Your dual plumbing cannot reach one another.
Scenario #2
You are fully capable of self-interlocking.
For me, I'd love to be in scenario #1.
