A mom shared this photo below on Imgur, with the caption "My son's Chipotle cup says 'reproductive sex' on it." This is a fairly neutral statement, though there are other words on the cup. She could have written, "My son's Chipotle cup says 'cultivating thought' on it." Or "My son's Chipotle cup says 'who wants to feel so small?' on it." Therefore, we must assume the words "reproductive sex" have some significance to her, though they are the least sexy words about sex ever strung together.
