Listen up, gentlemen. It’s time to start pleasing your ladies. A recent study from Indiana University found that 85% of men said that their partner had an orgasm when they had sex—while only 64% of women said that they themselves had one. Oof. Bottom line: while you think you might be pleasing her, more often than not, you’re missing the mark. “Women know that most guys want them to reach O-land, and they don't want to disappoint,” says Dorian Solot, a sex educator and co-author of I Love Female Orgasm: An Extraordinary Orgasm Guide. “So all too often, women fake orgasms, or just let their partner assume they had one.” If you want to guarantee the real deal, stick to these nine positions that will work every time.
