4yr olds minced words

is it really nescessary to pull there foreskin back to clean or is it just an oldwives tale? my aunty told me that i should be, i was like omg i never had, and shes like oh well your lucky he hasnt had an infection, the midwife at the hospital when he was born told me it wasnt nescessary does it change when there older

i tried to teach him to pull his foreskin back to clean it in the bath the other day, he was getting dressed and asked me if i wanted to play with his penis again........ OMG
i explained that i wasnt playing with it i was showing him how to clean it..................
this question asked in front of the wrong person could get me in a lot of truble,

thank god for that, its amazing how the answers change through the generations. when i asked my mum she was like, "when i got you and your brother (my brother was two at the time) he had a really bad infection and had to be circumsized (at two omg) so yes you should be",im like *groan* mind my brother and i were badly neglected by the time mum got us and would have been lucky to have had a bath with in the last two weeks,
think i will stick to your answer sound more refreshing and updated, thanks caro
