i found about retracting the foreskin like 4 months ago, and i stopped retracting to clean lately because i'm too lazy, will i get any diseases or anything? and smegma, does it do anything? I hate smegma, damn annoying and gross. i've been reading this, and im still not sure wat phimosis is... what is it? srry, maybe it was explained above before but i cant find the definition lol. what is it?
