HELP White vagina/itching

I've had sex with two people my whole life.

Two times with someone 10 months ago and now with my husband.

We've been on a roadtrip for a week

We went to the beach and we got new condoms during this trip. The rest was spent in a car or hotel room.

We accidentally used flavored condoms that were in a pleasure pack for intercourse.

We also had sex without a condom once, but he pulled out.

I've been itchy for the past couple of days, and we noticed last night that my vaginal opening is now swollen and white. I'll post a picture if needed. Any ideas what it could be?
