No matter how advanced your bedroom smarts are, there are always new frisky facets of men to be unearthed. “We don’t give guys enough credit for how multidimensional their sexual lives are,” says Erika Pluhar, PhD, a certified sexuality educator at Emory University and coauthor of Sexual Etiquette 101. “And because of that, surprising things can go undiscovered.”

And we wouldn’t want that to happen! So we asked sex experts and guys themselves to divulge men’s innermost sexual thoughts and behaviors. The result? Ten revelations that will help you understand—and excite—your guy like never before.

1 You’re Not the Only One Who Has Faked it

Now and then, men can’t get over the brink for the same reasons women can’t—they’re tired, stressed or the urge just slips away—so they pretend to peak. “If I don’t climax, my girlfriend works hard to make me, which is awkward for both of us,” says Jay*, 26. “So once or twice I’ve faked it.”

Yep: Surveys by Durex, ABC News, and Britain’s ITV network all found that 11 to 19 percent of guys have put on an act. If it happens, it’s no biggie, plus you probably won’t even notice—especially with a condom. (If you suspect your guy is faking regularly, it could be medical, so urge him to see a doc.)

But if his overall enthusiasm is flagging, sex is probably becoming too predictable. “Try seducing him in the kitchen,” says Joan Elizabeth Lloyd, author of The Perfect Orgasm. “Counters are a perfect height for oral sex.”

2 They Want You to Take Charge in Bed

We’re not telling you to break out the whips and chains (yet). Just call the sexual shots sometimes. “Men feel constant pressure to perform, from seducing you to pleasing you in bed,” advises psychologist and sex therapist Joel Block, PhD, author of The Art of the Quickie. Being passive lets them focus fully on their enjoyment. Mark, 31, concurs. “I love when a girl grabs my head, kisses me hard, and starts stripping me,” he says. “I know she wants me, and it’s a thrill because it’s not typical behavior.”

So show him your naughty side. Surprise him in the shower with a wet ‘n’ wild quickie. Make a sack session all about his pleasure. Seduce him when he least expects it, suggests Lloyd: “If he’s watching the game, sit on his lap to block the TV, kiss him with lots of tongue, and start playing your own ball game.”

3 They’d Rather Log On Than Put Out at Times

It might feel crappy when a guy would rather play a video game than play with you, but it’s not uncommon. “When I’m on my XBox, I can’t imagine stopping,” says Andrew, 28. “It’d be like eating chips and having someone suddenly take them away. You have to be ready to stop, even when your girlfriend is lying there half-naked!”

If it’s any consolation, it’s not personal; it’s a physiological response. “Trying to beat a game releases testosterone, which makes guys want to keep conquering, despite distractions—even dirty ones,” says sexologist Ava Cadell, PhD, author of Dr. Ava’s Tantra Workbook. So if your guy’s more plugged in than turned on from time to time, let up, and let him play. Who knows: The increased testosterone he’ll have once he finally shuts down might even leave him primed for a randy postwin celebration.

4 They Measure Their Manhood Two Ways

Though guys often joke about wanting a bigger penis, a recent study by a UCLA researcher found that a whopping 88 percent of guys consider their packages to be average or big. But if they’re cool with their size, why all the penis-enlargement spam? Turns out, some guys may be insecure about their erect units. “Men know how their flaccid penises compare to other men’s because they see them in locker rooms,” says David Frederick, a study coauthor. “But the only other erect penises straight guys see are the huge ones in porn.”

Of course, men know if they’re under average and may be sensitive. If your guy is small, try positions that allow for deep penetration. Doggie-style gives him maximum access, especially if you lower your chest. In missionary, put a pillow under your pelvis, and rest your feet on his shoulders. For girl on top, grind in circles – not up and down – to prevent slippage. To boost clitoral sensation, rub against his pelvic bone. With these tricks, size won’t matter…much.
