Talking is an incredibly persuasive form of oral sex. Try to create an atmosphere of trust in which she can shed her images of "foul fellatio." (It doesn't hurt to practice what you preach. Do onto others as you would have them do unto you.) If your lover is bothered by the flavor, have her try an erotic hors d'oeuvre: artichokes. No kidding. Scientists at Yale found that eating artichokes improves the flavor of whatever follows. Dousing the swizzle stick in brandy or a flavored liqueur will also help. (Why not an artichoke liqueur?) Others use whipped cream. If your girlfriend fears gagging, start slow. Suggest she wrap her hand around your erection and lick or suck the head and shaft. That puts her in control, which may ease her inhibitions. Don't insist she immediately take you full in her mouth and perform with the expertise you see in porn films. Let her go at her own pace, and double your effort to reassure her. (It can be lonely down there.) Moan. Stroke her hair. Tell her how good she makes you feel. Don't whine for more when she's had enough. You'll probably find that once she's overcome her initial reluctance, you won't have to ask a second time. The more you do something in sex, the looser you get, the more inventive, the more comfortable and, in general, the more willing to try it again.
