Hello, doc i just wanna ask , i have white blisters on my foreskin its been there for years(itchy sometimez), i have similar on my lips, what is it?

Fordyce's spots?: These described lesions are most likely not blisters but small spots of variable size of 1-3 mm. If so, they may represent the occurrence of Fordyce's spot, which are the ectopic sebaceous glands and not related with hair follicles. Of course, it is hard to tell with 100% accuracy without a direct look at. If still in doubt, see urologist or dermatologists. But still ask if you have long foreskin.
