Thanks))

Oh yeah, Kant was against anything that used people as a means to an end, and he considered masturbation as an instance where the person is using his own self as a means to get pleasure.

People often caricature him (myself included), but I believe there's something deep and meaningful in what he was saying, especially as applied to other forms of 'using oneself as means to an end', e.g. when a woman treats herself as an object, e.g. commercializes herself, makes herself and her body into a brand, in order to capitalize on it.

I use the fem tag cos I think what I write about in the sex differences posts almost always relates to something feminists talk about. It's actually one of the main reasons I was interested in sex differences, in order to gain a thorough scientific understanding of sex differences which will ground my feminism (and my much deeper study of it in the future) in reality.
