Nudity is not, by itself, erotic, and nudity in mixed groups is not inherently sexual. Sexuality is a matter of intent rather than state of dress. Nudity is sensual, it simply feels good.
Countries with fewer hang-ups about nudity have lower teen pregnancy and abortion rates.
Clothing focuses attention on sexuality, not away from it. It often enhances immature forms of sexuality rather than promoting healthy body acceptance.
Complete nudity is antithetic to the elaborate semi-pornography of the fashion industry.
Naturism where everyone is accepted is antithetic to the body fascism where only “the beautiful people” can be seen nude.
