Itching is not a typical symptom of HPV or warts. If you had itching when you had the warts, it probably was just a coincidence. Even if warts/HPV cause once in a while, other things are more likely.
As you seem to realize, candida (yeast) infection is always a consideration; it is the most common cause of vulvar itching overall. Contrary to some beliefs, most yeast infections do not cause much increased vaginal disharge. BV does not cause itching. It can be pretty easy to miss yeast by standard diagnostic tests, so you might check with your doc about how certain s/he is that you don't have candida; and whether, if there is any doubt, it might be worth trying one of the over-the-counter yeast treatments.
In any case, there is no particular reason to be concerned about HPV/warts. Because you are a sexually active person, the odds are fair you have HPV. (A brand new, population-based research study shows that among women age 18-25 in the US, at any point in time about 25% have an active HPV infection.) But sexually transmitted HPV is basically unavoidable, and since the vast majorty if infections do not lead to any important health problem, in my opinion there is no point in getting worked up about prevention.

Don't worry so much about your partner catching HIV from you. It probably won't happen, but if you are infected and he catches it, he probably will never know it. We all get HPV somewhere along the line; it is a normal part of being sexually active. But if you want to take precautions, use condoms. Consistent and proper condom use is highly protective.
