Hello. Welcome to Just Answer and thank you for the question.

You need to answer a few questions first which will help me assist you in a better way.
Did you have an STD screen done?
Any itching in the affected area?
No i have not had any STD screening. No there is no itching in the area at all or pain or irritation.
Thank you very much.
This does not sound like an STD however, any such lesion on the penis or scrotum in a sexually active male should direct an STD screen to be absolutely sure about this.
There is a likely possibility of a sebaceous cyst in your case.
A sebaceous cyst may persist for months until this opens up and releases the cheesy material in it.
This need to be excised surgically as this may get infected and can recur also if this opens up and releases its contents in the scrotal skin.
If not already, you must have this examined by your doctor discussing the details i have mentioned to chalk out further management plan.
Keep the affected area dry and clean.
Wish you good luck.Kindest Regards.

Is Molluscum Contagiosum a possibility? Seems like a sebaceous cyst would be in the deep tissue this seems more superficial like a pimple.
Molluscum Contagiosum is unlikely here as this commonly affects the people with Immune deficiencies like HIV.
Moreover the lesions are usually multiple and tend to spread, if left untreated or undiagnosed.
But honestly, with out a clinical examination, and at times even with out a biopsy of the lesion, a specific diagnosis can not be ascertained, that is the reason why i emphasized to have this examined soon.
