Yeah, I can't tell if she is talking about air in the vagina, or actual lumpy bubbles of flesh in her vagina, or what.
If you're talking about air in the vagina coming out and making noise as if you were passing gas, that is normal.
If you are talking about bumps, as in some sort of growth, I would have it looked at by an ob-gyn. If you are having sex, you should already be seeing an ob-gyn anyway.
