Three's the magic number, “School House Rock” once declared.

So it would seem those purveyors of education were correct, in ways they probably never imagined. In today's dating world, there's the feeling that we have unlimited choices about who we date, love or decide to take home for a good time.

We can also decide how many people to include in our exploits. And lately, it seems like more people are expanding their options.

I know a number of people, many of them women, who have had threesomes. By threesome, I mean three people who share a sexual experience. Typically, these are not romantic encounters. For some they are one-time college experiments. Others continue to participate because they downright enjoy them.

“For me, life is too short,” said one female acquaintance I asked about the matter. She has engaged in “six to seven” threesomes in her life. 

The point of the encounter, she said, is to have a good time. No hang-ups and no second-guessing, all foreign concepts to myself but noble goals nonetheless.

“I just try not to let jealousy enter,” my friend said.

Is this the future of relationships? Threesomes seem so mainstream — in entertainment or even in conversation — you could practically buy them in bulk at Sam's Club.

Sexual adventurousness is nothing new. Open a history book or look closely at a Grecian urn. You'll that sexual escapades have been passed down through the ages.

I know civil engineers, librarians and artists who have had threesomes. What they all share, and what amazes me, is their ability to separate the physical from the emotional. They seek what makes them feel good and go from there.

“People are so uptight about sex,” my friend said. “They are so uptight about expressing themselves and what they want and are so afraid of upsetting their partners. That's why people are miserable.”

Point taken.

The closer I get to the end of my 20s, the more I wonder, am I too busy freaking out about my hang-ups and guilt complexes?

As my friend said, “Don't let the thought of your mother hold you back.”

Those are wise words from a wise woman.

I still want to be in a committed relationship one day, where my partner and I stick together and no one strays outside the pair. That's just me, and I'm fine with it.

I'm just glad these topics are on the table. Whether you are straight, gay, transsexual or someone who loves everybody, you have a right to get what you want and enjoy it.
