Geeze doesn't everyone masturbate? If you don't I think that strange.
My dog masturbates:)
And it is NATURAL to want to masturbate by looking at the naked people and people having sex! We are attracted to people - duh! Its a craving like eating!!!!
SEX is normal, not sinful, not dirty, and not something to not mention.
The reason there is so much repression and a problem with it sex /nudity - is that RELIGION has told people that sex is sinful and that the body is dirty for thousands of years!!!
Fuck Religion!
