I have 1 girl and 2 boys and love both sexes the same, neither of my boys mark or hump! I do agree that the girl clothes are cuter but my girl is more independent while the boys are more loving and cuddly. I think having both you get the best of both worlds
I think people get themselves way too worked up about boys marking, I think its because for example you see threads on here with people moaning because their boy is marking but really what % of all the boys on here is that? I mean nobody is going to start a thread saying 'My boy does not mark yay!' are they?
