Since you’ve recommended in previous columns that a person not go directly from anal intercourse to vaginal intercourse, I am wondering if I can go from analingus to cunnilingus without spreading germs. Also, can I still orally pleasure my girlfriend’s ass after I’ve used lube to penetrate her, or is that bad for me?
–More Than A Mouthful
The reason that going directly from ass to pussy is not a good idea is because you can introduce bacteria from the rectum into the vagina, where it will cause an infection. There is a much greater risk of this transfer of bacteria during penetration because your dick has been inside the rectum (the deeper you go, the more likely you will come into contact with bacteria or trace amounts of fecal matter).
When it comes to oral stimulation, if you are simply licking the outside of your girlfriend’s ass, then her outer lips and clitoris, there is less (but not zero) risk of cross contamination, as long as her ass was clean to begin with. If you want to be super safe, you can rinse your mouth out with mouthwash in between oral acts. Once you have penetrated her ass, you can still orally pleasure her, although I recommend a quick swipe with a baby wipe or damp towel just to clean any lube that may have come out of her ass as you withdrew your dick. Also, pick a lube with a taste that either doesn’t bother you or you actually like so if you do get a mouthful, it won’t make you wince.
