Am I a bad mom? Kind of long

So my DH and I have 3 BOYS.we are trying to raise them right.respectful,mannerisms,polite and be them selves.

So here is where I'm a bad mom.a so called friend.my 11 year old is very responsible doesb chores and now I'm teaching him how to cook iron sew (things girls are supposed to do according to friend)I want my son's to be independent and not to be mean but rely on a women to do things for them per say I want my son's to know how to do things.(SOME Women now days don't know how to cook,clean etc)I won't be around forever and all I want is for my boys to be good men of society and find a partner who will make then happy.my son knows about sex and I tell him that if he ever has sex use protection don't ever take a word of a girl who says they're on bc.just be smart and responsible.I tell him be a faithful man if you want to get around be smart and don't string along girls.my DH tells him and gives him manly talks.I guess I'm just preparing my son for the real world.now my so called friend says I'm a bad mom because I talk to him about sex, dating, teaching him how to cook or do chores.he's a boy and no need for him to know how to sew.that an 11 yr old is to young to know how to cook.I may be a bad mom like I tell her but at least my son will know how to take care of himself in the long run.she is a mother to two boys 13,17 and I don't tell her about her parenting ways even though I can sit here and say some bad things but I won't because Its not my place.so am I a bad parent influencing my son in a bad way.I so ready to tell her off but I can't because my DH is bff with her DH.
