Then you'll be all mopeing all over the place, "Waaah! it's not tight anymore, it chafes against my dress, blah blah. Be happy for that beauty that you have and keep it covered and tight
this situation is called 'Phimosis' . can be treated either by partial operation, or regularly pull back the skin when it's semi hard. initially it will hurt & can be bit rupture on skin. give few days gap & use lotion. over the time it will become normal. or better you see a doctor (urologist or endocrinologist) for operation or suggestions. Google search the term for more info.
