When doing a DP one penis is all the way in while the other is almost all the way out. Then the one that is out goes all the way in, as the one that was in goes almost all the way out. The 2 penises "See-saw" in and out. Therefore only one is in all the way at a time, and both will also be halfway in on the way in and out.
We were gentle at first since it was her first DP. We did a see-saw DP to start and she completely loved it!
