Hello and welcome to HCM
The cysts that you have mentioned can even in people who abstain from sex.
These cysts are filled with pus like material and are painful on touching. Presence of pus indicates some kind of bacterial infection or some viral infection which has developed superimposed bacterial infection
Viral infection is commonly called 'genital warts'.
Other possibilities are infection of hair follicles, sebaceous glands or infection of Bartholins gland.
Exact nature of the lesion can only be determined after examination.
The pus from the lesion should be cultured. Culture of the pus will determine the organism causing the infection and culture sensitivity will help to choose the most sensitive antibiotic.
Thanks and take care
