Hi there. From your description, it does appear like a 'molluscum
contagiosum' affliction. It could very well be a cyst
involvng one of the myriad glands situated in that region. So if your gynecologist is not worried, then it is probably benign & harmless. Perhaps your gynec is too busy & unless specifically questioned about it, possibly has much more 'serious' issues to consider. I would recommend visiting a dermatologist
, get it assessed & permanently dealt with. A tiny local injection followed by an ablative electroacautery & excision of the lesion is probably the way forward to achieve closure on this subject!!
Cheers & wish you good luck & Good health. Do practice safe sex
