Sex advice with Suzi Godson: I think my girlfriend fakes her orgasms

She is smart, funny, and beautiful, but I suspect that she fakes her orgasms because her climax is too perfectly timed and the noises she makes are not particularly convincing. I feel really awkward asking her if she is faking, but it’s just as awkward pretending that I have not noticed.
The “fake” female orgasm is a phenomenon that has generated a great deal of anxiety, hype, and speculation. In a recent study, catchily titled Faking Orgasm Scale for Women (FOS), the psychologist Erin Cooper asked women aged between 18 and 31 about their motivations for faking orgasm during sexual intercourse and oral sex.
