There's a whole lot of information on how to arrange a threesome, but there's very little about what you should do once you're in one.

Threesomes are not like regular sex, they require both imagination and sensitivity. If you plan on having a threesome, you need to go into the situation with some idea of what you're going to be doing.

Understanding these basic rules will help you avoid some common mistakes so you can get the most out of your threesome. There are various types of threesomes that you can enjoy, but the most common is with two women, one of whom is likely your bisexual girlfriend or wife. These are the basics on how to handle such a situation.

Rule 1: Establish the rules
You're going to have sex with two women and all three of you have your own rules and limits, so understanding and respecting each other's comfort levels should be a top priority.

Because your relationship with your woman will likely be affected by this new experience, you need to be absolutely clear on which acts she's comfortable with -- and what to avoid doing -- in advance. She may tell you that she's uncomfortable with the idea of you penetrating another woman or even pleasing another woman orally.

You must respect her limits. Remember; each woman may suddenly feel jealous, so try your best not to shut either woman out.

As well, you may end up feeling jealous if you're not the center of attention. Just keep in mind that the object of the game is to share sex between three people.

Also keep in mind that although some people try to drink their way to bravery for a threesome, drunken sex usually turns out badly. If you want to have a cocktail or two to loosen up, that's fine, but no more. You want to be at peak performance.

Rule 2: Be as giving as you canAlthough you may be hoping that the two women will give you 100% of their attention, realistically, they're there to please each other as well, so you may end up feeling ignored.

The best way to approach this situation is to forget your feelings for a moment and try to be as generous with your hands and mouth as you can.

Pleasure in one-on-one sex goes back and forth, but in a threesome it's more of a cycle that moves from person to person. So be patient; focus on turning both women on and the attention will come back to you.

Whatever pleasure you get in a threesome is a treat, so instead of expecting anything in particular (like getting oral sex from both women at once), enjoy everything that comes your way.

Keep your hands moving and make sure you know when to penetrate.

Rule 3: Keep yourself busyWhen you find that both women are busy pleasuring each other and you have nothing to do, keep yourself busy. Take matters into your own hands and find something to do.

Caress the breasts, thighs or vagina(s) of one or both women, kiss their backs or necks, or give oral sex to one if she's in a position that allows you to (believe me, this will redirect attention toward you in a hurry).

If you decide instead just to pleasure yourself for a little while, don't feel bad; the action will come back to you soon enough.

Rule 4: Be careful with penetrationPenetration is what novelist Tom Robbins calls "that old show-stopper." It automatically forms a serious bond between you and one woman, leaving the other out. For this reason, use penetrative sex only when you're sure both women are comfortable with it.

Your natural inclination will be to pay close attention to the woman you're having sex with, but you mustn't focus on her entirely. This is about the three of you, so keep that ideal close at hand. Kiss and touch the other woman, look her in the eye, and talk to her if the mood is appropriate.

Be aware that you may feel overwhelmed with pleasure if you're thrusting into one woman and kissing and caressing another, meaning that you might climax more quickly than expected. Take it slowly and pace yourself.

And don't get so excited that you lose track of the women: all three of you should be sexually satisfied and even if you achieve climax first, you must do everything you can to bring your two partners to orgasm.

Rule 5: Be safeCondoms are a necessity, obviously. Semen, vaginal fluid and menstrual blood transmit STDs, so use one specific hand to pleasure one specific woman and use the other hand on the other woman -- and keep it that way. You must never alternate.

Likewise, if you're having intercourse with both women, you must also use a separate condom with each partner. As well, dental dams are a good precaution for oral sex. Lubricate the side that you place against a woman's skin for better sensation.

it's not a relationship

Afterward, lie around with both women in post-coital bliss. But remember, it's not a relationship. Which means that the third person likely shouldn't sleep over. It may seem like a great idea in the moment, but prolonging a threesome is a recipe for total disaster.

Be reassuring to your girlfriend or wife. You've had fun, but it's only pleasure and experimentation. Tell her that she turns you on, that seeing her being pleasured by another woman aroused you, and that while you enjoyed yourself, there's no one for you but her. She's your primary concern, so let her know it, and you may well have more threesome adventures in the future.
