it is a tertiary attraction where one has the involuntary urge to derive erotic pleasure from a subject to satiate one's libido. it involves the desire to receive erotic pleasure through masturbation, sex, or even through mental stimulation. erotic attraction often causes physical arousal or other physical effects such as a faster heart rate and heavier breathing.
erotic attraction differs from sexual attraction which is the broader desire to engage with sexual activities with an individual in any way. sexual satisfaction is the enjoyment of a sexual bond between people and the acts surrounding it, and it concerns maintaining a healthy relationship and emotionally fulfilling sex life. erotic attraction is more personal and simple in nature, involving the very primal need to receive pleasure.
sexual attraction may not always involve erotic attraction; one may have the desire to engage in sexual acts with an individual, but these desires may not be erotic or arousing in nature. erotic attraction is usually derived from sexual attraction, as sex typically leads to sexual pleasure. however, in some cases, erotic attraction may arise without sexual attraction being present at all, especially in kink/bdsm.
it should be noted that most people inevitably become aroused if they are touched in a certain way regardless of their erotic investment in situation. erotic attraction is mostly to do with preference and satisfaction. someone may still feel erotically unsatisfied even if they become aroused or achieve orgasm. erotic orientation is to do with how someone prefers to achieve erotic satisfaction.
lacking erotic attraction is called anerotic. having normal erotic attraction is called allerotic.
i am not comfortable with coining "hypererotic" as it would likely be a part of hypersexual disorder. i am not hypersexual myself but people who are are welcome to coin hypererotic and go into depth with it.
one may have a differing sexuality from ones eroticism. someone who enjoys having sex but does not experience arousal or libido satisfaction from it may be on the anerotic spectrum. someone who does not experience sexual attraction to others but does experience arousal & satisfaction from having sex may be asexual and allerotic. someone whose sexual and erotic orientations match are erexic. erexic can be considered a conformant term, as it's the typical and expected way for sexuality and eroticism to manifest for an individual.
