I like to take complete control, or conversely just lay there and let the other person take all the control or do all the work). Another way to say this is let the hornier partner take the lead and keep the less horny from getting in the way. When I am in control, I fantasize about being with a younger, sexier, inexperienced partner. When I give up control, I fantasize about being with an older, more stable, experienced partner.
I will start this next paragraph by saying no one should ever be raped, period. Nevertheless, under consensual mutually-satisfying relationships, some people enjoy talking up a rape fantasy or may even partake in some progression as part of role play. This is where one-way rough sex comes up. One person just taking the other. Or one person is just being taken by the other. My paragraph above fits two moderate aspects of this. And I will warn that this often requires the role play “aggressor” to ask “are you ok?” once in a while. This is because the game can sweep things up and be so safe yet intoxicating that the recipient can sound like they are being hurt even when they are experiencing pure sexual satisfaction and nothing else.
Which brings me to the point of why do rape fantasies exist? There may be 50 answers to that. They may span from mundane laziness (have the other person do all the work), to the indulging vanity of validating your desirability, to not having to be responsible for the hot sex if coming from a conservative upbringing. You can add bondage to further spice up the last one. Heck, bondage and a pre-agreed safe-word can go far here.
I would like to hear from others for other reasons why having an aggressive partner would turn them on?
