Hi,
This could be folliculitis, acne, pimples, fordyce spots, bacterial or fungal infection, dermatitis or genital warts.
Nothing can be said with surety without having a look at the lesions and a clinical examination.
Wear lose clothes, maintain good personal hygiene, apply calamine lotion at the sites of the lesions.
Do you have any other associated symptoms? You should consult your doctor for a proper clinical examination.
Let us know about what your doctor advises and post us about any other doubts that you might have.
Regards.
more information, doesn't sound like any STD herpes is possible but you would have small blisters. Then it wouldn't be on your eyelid under normal circumstances.
