Hi I've been masturbating since I was about 13. I'm 16 now and only just managed to get my foreskin back. Its pretty smelly, i've cleaned off all the smegma but i still have a white area at the top of my head which i think is some hard seman. I've tried for weeks in the shower and bath trying to clean it off but it won't come off. I've tried soap and baby oil but nothing works. Any suggestions?
