What sex feels like for him: during a sack session, a guy is overwhelmed by a range of sensations. Here, men describe them ... and how you can double your dude's bliss.(Love & Lust)

Let's face it: Guys are simple creatures, and ultimately, pretty much any kind of sex is going to put a smile on your man's face.

But that doesn't mean that every move and stroke you treat him to feel equally as good. Truth is, even though the typical dude doesn't articulate it, certain things a woman does to his body at specific points during a pleasure session feel a hell of a lot hotter and more intense than others. We're talking about tiny-yet-very-effective tweaks to positions and touches that mean the difference between pretty-good booty and stratospheric, I-see-stars action.

Wanna know what they are? We thought so--which is why we got these real guys to spill the beans on the secrets of male arousal.

Erection Triggers

* "When a girl kisses me passionately or runs her tongue in a frenzy up and down my chest, I become hard almost instantly. It's mainly because she seems so hungry for me."--Kevin, 36

* "Even if you've been with the same guy for a while, never underestimate how revved up he'll get seeing you strip. There's something hardwired in the male brain that makes watching a woman take off her clothes insanely thrilling."--Justin, 29

* "My girl will sit on my lap while I'm at the computer. She'll position her hair and neck in my face so I breathe in the scent of her body. Within seconds, I want her so bad."--Scott, 26
