Good advice on how to learn to have multiple orgasms

What if nothing happens? That’s fine! The point isn’t to tally up as many points (read: orgasms) as possible. The point is pleasure.
As O’Reilly says, “Experimenting with new techniques and approaches can be fun, but don’t get hung up on counting your orgasms!”

The bottom line The process of learning whether you or a partner can have — and potentially having! — multiple orgasms can be incredibly pleasure-filled.
Even if you don’t have an orgasm — or “only” have one — chances are you’ll be making some “oohs” and “ahhs” and “oh-so-goods” along the way.
