'why do we long for sex so much?'
because you produce at least 1,500 sperm cells per second & they need to go somewhere

Had you ever considered that could be down to jealousy? A woman who has conformed to the ideology of 'society' or 'religion' all her life, despite her natural desires, or needs is going to feel resentment to the woman who doesn't deny herself the pleasures she wants.
It's a case of redressing the balance. You're not allowed to be that person and it is so completely ingrained that the very thought of a woman having sex with multiple men is sickening to the point that if discovered, then you would have to burn the bed, even if no one actually got into it for what it symbolises.
It is amazing just how much contempt a person can have for another when sex is involved and I'm afraid that contempt tends to be pointed at the female species more than the man and we're not even as messy as you guys!!!!
