Once, years ago, I slept with a woman who, when I finished, suddenly hugged me very tightly, in a way that felt oddly protective. I mean, like hugging me like I was her child she was trying to protect from a bear. At the moment, it made me feel uncomfortably vulnerable, like she felt she had to protect me during those seconds where a man is totally helpless. But a female friend just suggested, it was her breeding instincts kicking in, even though I was wearing a condom. Is this a thing?
