Hi, about a month ago I observed some very small white grains (like needle heads) just at the edge of my penis glans under the prepuce. They are just a few in number and present like a semi ring. Sometimes these grains become a little itchy as if some needles are being pushed there. Also, the smega deposited underside the glans has increased in quantity and is very foul smelling. Earlier it used to be almost negligible and without any foul smell. None of these was present before a month. Can you please help me out.
