Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Hormone active (endokrine) substances are a real problem in ecology in particular in regards towaste water treatment. They often can already take effect on ng/l concentrations.
They are not put there deliberately to turn frogs gay, but they are the result of necessary uses like hormone treatment and unecessary uses like hormonal contraception or use in cosmetics.
I have no doubt that it was presented poorly by Jones and with ulterior motives, but endokrine substances emitted by human activities are a serious issue.
What are the other options?
Condoms.
With the great side benefits that they also protect against most STDs.
Until they don't.
I take that over no protection against STDs.
Of course you should think about who you have sex with in regards to STDs either way.
