Or better yet, actually have lived a little as a teen when you were young enough to bkinc eback quickly and easily and known by adulthood exactly what your limits are and what dose will give you the best time.

But failing that, for the people who waited til adulthood to remove the stock from their asses, yes, there are many ways to learn what you should start with, among them: asking the people who sold it to you (they have a vested interest in making sure you have a good time so you’ll buy more), asking the people you’re doing it with (they probably removed the sticks from their asses long enough ago to have some idea what’s what), and yes, even Googling it.
