HE WANTS MORE SEX

Yes, maybe he's just extrahorny or you're looking extrahot, but a sudden surge in his sexual appetite can also be a sign that something's awry. "A man who's hiding something won't want to con nect emotional ly th rough conversation because he's afraid if he does, he'll spill the secret," says Krista Bloom, PhD, a psychologist in Florida. "Instead, because he loves you, he'll look to fill that void byconnecting with you physically." But since various things can cause a spike in a guy's sex drive—like an awesome shift in your relationship sparked by, say, getting engaged—don't accuse him of anything without ruling out other explanations.
