It sounds like you have BV. It causes discharge and a gross almost fishy smell. This is normal, your hormones are changing and you're probably producing more yeast than usual. There's a pill form of medication that can be prescribed for you if you don't want to use the cream then ask the doctor. My advice on the spot, would be to show your doctor and your mom. Visit a gynecologist, it's embarrassing to show someone that part of your body, but it's better to be safe than sorry. And all women have to. As far as the sex thing. I'd steer clear of being with any guys for a long time, even if you think you're in love. Waiting until marriage is the best because you care about that person more than anyone. If not you usually end up breaking up with the guy and regretting ever sharing that part of yourself with them.
And please don't worry about sex or oral sex! Why are you even talking about that?!?!? And birth control pills should be discussed with your mother (or a woman you trust). Stop talking to other kids about such important issues about the body! Be responsible and do what your doctor says!
Why aren't you talking to your mother or an aunt about this? Why cousins? You should have been MADE to return to the doctor for the yeast infection cream! If you do not you can have it get worse because you haven't followed the doctors orders. They are the doctors, not you or your cousins or us. Please talk to an adult woman that you trust. The rest of us grew up talking to our mothers, aunts or women we trust-you should do the same. And you should listen to your doctor. You can cause so many infections when you don't responsibly take care of your body-inside and out. ALL of us have had yeast infections and have used the cream. It's a part of being a female-it's life.
Please talk to your mother or aunt or woman you trust. Talking to people that are close to your age won't do you any good. They know just about what you know.
