It sounds like Bacterial Vaginosis to me. Has she always had this odor or is it something fairly new? If it’s somewhat new, that’ll be a way for you to bring it up without feeling uncomfortable. Just say something like: “Do you smell kinda different, or am I imagining things?” It’s not accusatory, just curious, so it shouldn’t hurt her feelings.
Yeast infections don’t generally smell and are typically accompanied by burning, itching and redness, so if she’s physically comfortable with you going down on her, it’s most likely not a yeast infection.
I’ve had BV before, so I know the symptoms. Once you bring it up, talk to her about what they’ll do when she’s seen by a doctor. She may not have brought it up simply because she’s too embarrassed or she’s worried about what they’ll have to do to fix the problem. And trust me, it is really embarrassing because what chick wants to say their crotch smells like rotting fish? But, it happens to many women and it’s completely treatable. Let her know that it’s not her fault, either. It has nothing to do with hygiene like a lot people think it does.
Anyway – when she has her appointment, she’ll tell them the symptoms. Smell, color and consistency of discharge, etc. Literally all they’ll do is swab the inside of her vagina, test it under a microscope, come back to the room and confirm she has an infection. From there, they’ll prescribe antibiotics. Pretty easy and it goes away quickly.
Now, something your girlfriend should keep in mind is that once a woman gets BV, almost all women get it again at some point. There are things she can do to keep it ay bay, however:
*Tell her not to wear thong underwear. Any fecal matter that moves from the back of the strap to the front can cause an infection. If she likes cute underwear, I suggest boyshorts. Cotton is always best, because it’s breathable material. (Infections like dark, moist places.)
*Buy lots of yogurt and tell her to eat it some every day. The more live cultures, the better. Danactive is the best she can buy – no one out there makes yogurt with as many live cultures.
*If she does douche, tell her to stop. Doing so kills the natural, good bacteria that it takes to fight off infections. The antibiotics will also actually kill the good and bad bacteria, which is why yogurt is really important, especially while she’s on the medication and for right after.
*There’s a product on the market called RePhresh that apparently works wonders for women with this problem. It’s cheap and can be found on practically any isle that carries products for women. They’re gel inserts that women use once every three days or so and it keeps the pH levels balanced and infections away. The product does not cure the infection – it’s for use after someone has taken antibiotics. If you give her oral sex after the infection is gone, tell her to use it right after. Saliva can actually disrupt the natural balance of a woman’s vagina. Semen can, too. No sex toys, unless you know they’re very clean. If she uses the the product – sex is fine and oral is fine. People say it actually makes a good lubricant. It’s odorless and tasteless, so you shouldn’t have a problem with it, either.
*If your girlfriend has a pretty sugary diet – it needs to change. This kind of infection thrives off of sugar.
*Finally, men do get BV and they can give it to their partners. They’re simply lucky because they can’t display the smelly symptoms. So, if your girlfriend ends up getting this again, there’s a chance that you yourself have it. Taking the medication to rid yourself of an infection is a good idea. So when your girlfriend goes to be seen, it might be a good idea for you to go and also get a prescription for the medicine.
