I have a lump on my mon pubis, i am 16 years old and not sexually active. there is only one lump and it is small, it is only uncomfortable when poked?

Needs an exam: Lumps, bumps, blisters and other skin abnormalities on the genitals need to be evaluated. An examination will be needed to know the cause and treatment. It sounds like you may have an ingrown hair or a small skin infection. Consider a virtual visit with an image of the area and a doctor on Healthtap may be able to give a more individualized answer

Hard to say: It is difficult to tell you what it is without seeing it. It could be a hair follicle "pimple" but that diagnosis requires a "viewing" which is impossible in this venue. If it enlarges or starts continuing pain see a GYN MD for evaluation.
