Breasts are highly sexualised in Western society, but particularly in the UK. Overly so. More than necessary.
Do men get helplessly aroused when see a woman breast feed? No. Because of the context. Because of the cultural norms.
The objectification and sexualisation of women and young girls is epidemic.
Propagating the species aside, the purpose of a woman is not to be sexually objectified by men. It's dehumanising.
And whilst men might be attracted to breasts, encouraging young men and boys to only view women through the filter of sexual attraction is what has lead to this epidemic.
Fuelled by ever more degrading porn, that any youngster can access at the touch of a button.
Educating young people about erogenous zones is neutral and mutually respectful information.
Asserting that breasts are there for men is not.
