Why is my vagina so bumpy? (Photo)

Yes. It's a problem with the sweat glands that irritates the hair follicles. There are various topical treatments that you can try. Find another dermatologist or gynecologist to get treated.

Fordyce spots can develop on the mouth and lips as well as the genitalia and can contribute to a bumpy skin appearance. They are normal elements of skin glands and are more pronounced in some people for unknown reasons. Skin resurfacing with peels and laser can reduce or eliminate their appearance but can also lead to changes in pigmentation and scarring if the treatments are too aggressive, like any laser treatment. In some cases it’s not possible to eliminate the bumps or they can come back.
For the labia minora, a labiaplasty can be performed to reduce the appearance and prominence of the labia. This procedure is very safe especially in the experienced hands of a surgeon who performs them regularly. Best to seek out a doctor who has experience with treating these issues. The labia surgery is ironically easier and more predictable than the fordyce spots treatments.
