All women can get yeast infections whether they've had a history of them or not. Are you really itchy besides the discharge? that's the hallmark sign of a yeast infection. Since you've never had a yeast infection before, I would really recommend you see your doctor for proper diagnosis. They can swab you and know immediately if it is yeast and then you can treat it. There are over the counter products that work well but for the first time, it's best to see your doctor. good luck
Symptoms of a yeast infection are hard to misread. There will be white discharge that looks like cottage cheese, and the itching around vagina will be much more than just a little Also, they will last till you treat them.
Odorless white discharge could be normal vaginal secretions. I'd look out for discharge that doesn't clear up on it's own, is like cottage cheese, or green or something, odor, and itchiness. if not, it seems to be normal.
It's a great idea to go see a healthcare provider a nurse midwife an OB/GYN or women's health nurse practitioner and just get tested for sexually transmitted disease your symptoms could just be from the irritation of having sex or you could have BV or chlamydia or gonorrhea and it's really hard for people to actually tell without a test.
