Brief Answer:
Bartholin's cyst likely.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
The causes for a large soft ball on the side of mons pubis could be one of the following:-

1. Bartholin's Cyst - Is located in the labia, and protrudes into the vagina and causes discomfort during sexual intercourse.

Bartholin's cyst is formed when a Bartholin's gland is blocked, causing a fluid-filled cyst to develop. Bartholin's cyst is not an infection, although it can be caused by an infection, inflammation, or physical blockage (mucus or other impediment) to the Bartholin's ducts (tubes which lead from the glands to the vulva).

If infection sets in, the result is a Bartholin's abscess. If the infection is severe or repeated a surgical procedure known as marsupialization may be required to stop further recurrences.

2. Infected hair follicles - can form small absesses, which can cause a small swelling, but they are associated with redness and throbbing pain.

Proper diagnosis requires a proper physical examination of the swelling in question. You might consult a gynaecologist who can examine and then decide on the appropriate treatment.

Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.
