Sir,i have some problem with my penis glans.height 6 & weight 54kg.at the neck of my glans some white white dotted structure are present for last 3 weeks.they are like small fine sand grains.it never pain or irritate me.i am 31 now.i have sex with my wife only so i think it is not a infection.i masturbate twice a week.is this causing the above problem.also during erection my foreskin automatically slides back,and in flacid state foreskin never covers the glans completely.it just covers about 90-95% of total glans.my glans is littile much thicker than my shaft.is it normal or i have some problem.what about the small white grains like stucture.there is accumulation of smegma ,as wash my organ every day.plz suggest..me most problem is glans penis move down. Thankyou
