My son is £ and 4 mths old. and his willy keeps getting hard....firstly is it normal for him to have this at such a young age? it happens when he's getting in the bath and plays with it, and he's currently led on the couch with a balnket over him but no bottoms on and is playing with his willy (normal i know) but he's made it get hard or as he says 'big' about 3 times now. my question is, is his forskin supposed to be able to strech over it at this age or not? the head of his penis doesn't look like it will come out of the foreskin as it looks very tight. will it strech with age or will he need (omg i cant think of the word for his foreskin cut off).....well will he need his foreskin cut off?
