What do you think Henry winter biggest turn on will be ?
above all, intelligence. beyond anything physical, it'd be you being able to prove how well-read, knowledgeable, and studious you are. impress him with extensive knowledge and he'd become enthralled with you immediately. of course, he would feel threatened and perhaps even irritated with a potential match, but with time, it would entice him all the more — he would want to steal that intelligence from you by clouding your mind and distracting you, most often in the form of shared intimacy and bone-shattering orgasms ;)
as for physical traits, well, i think it'd mostly be about style and disposition. refined, classy, possibly even lavish style in clothing; a self-assured air, confidence in your knowledge and decisions. being grounded. something along those lines. simple things — owning and maybe flaunting the intelligence you are sure you possess, just like him, would please him greatly.
oh, and clandestine, fleeting touch. a mere brush of the hand across his lower back in passing, an accidental caress of your fingers against the back of his hand. that.
