I went to find sources to disprove this but apparently it's real? I haven't been able to read through an article, but it seems to be common knowledge? I always thought sexual pleasure wasn't even possible until puberty began affecting the body. Is this legit, or are post-sexual revolution scientists and their cronies lazily coming to conclusions without any empirical proof that their interpretations are correct?
