Thanks for your query.Based on the facts that you have posted it appears that you have Fordyce spots
on foreskin and around glans penis
,These are due to accumulation of sebum in the sebaceous gland
beneath the skin.These spots are self resolving and do not need any treatment.
Please observe good personal hygiene and take high protein diet rich in Garlic,vegetables and fruits.If it gets infected or increases in size then consult some surgeon and get it excised under local anaesthesia.
