I do not know these, just guessing. But when people are sexual they typically get lots of influencies from the other person. If someone is skilled and used to trust one's own estimates on that area of life, if one via sexuality gets lots of inflyencies from an jntrustworthy person, one may err, but if one does not noyice those errors fully and in time, one maybe trusts those smaller skills like one's own and so one goes ashtray, into accidents and errors, and that way one can fall ill too, if one does not notice how big the differencies between people are and what each human type is like.
