Ever hear the expression, "A chain is only as strong as its weakest link."...?

A similar statement can be made with regard to a man's performance in the bedroom. Your love-making skills are only as good as the last woman you had sex with. If you received a standing ovation after doing the deed, to that woman -- you're the man! However, if your partner yawns and files her nails during sex -- you might not be the stallion she needs to quench her sexual thirsts.

Before you can crown yourself the hottest sex machine on the planet; and before you label yourself as inadequate because of a bad sexual performance -- make a mental note that not all women are the same and do not desire the same type of love animal in the bedroom. Just like most things in life, there are differences and preferences. Some women like it big, while others like it small. Some like it slow, while others desire the rapid fire approach.

Think of an unproven football player who excels on a small, high-school team. His skills are stellar against his peers, but his performance may not be so great at the next level. Over time, you may find your sexual performance taking on a similar feel. One woman's screams may be another woman's boredom.

You may askyourself: "I've never had any complaints, so why would my next partner not like what I'm doing?" If you're married, or in a long-term monogamous relationship, your sexual compatibility is already established as either good, mediocre, or bad. But, for those guys who think their skills are transferable to any woman, at any time -- you might want to talk to the woman in question.

As with most things in a relationship, communication is important when searching for sexual compatibility. Talking about it in the beginning is a lot better than finding out later that you've exerted a whole lot of energy for nothing.

Also keep in mind that technique is more important than some other issues men usually get blown egos about. You may have thrilled your last mate with a super-sized sex organ, but your new 4-foot 8-inch, 102-lb girlfriend might not be too comfortable with your extra longness.

Speaking of size, did we mention that technique is more important?

Sure - some women like them as long and wide as semi-trucks, but taking the time to talk with your partner about speed, frequency, location, and pressure -- will ultimately create a more satisfying sexual environment for both of you.
