What Does A White Growth Near Vaginal Opening Indicate?

I'm 21 years old. My Boyfriend has been here for the last 3 weeks, we had sex about 4 times. Yesterday I noticed a soft white growth near the entrance of my vagina and I think similar small ones on the inner labia. They seem easiky pulled off, but I'm worried if its genital warts or HPV or something. Please give some insight!
