As far as receiving suppositories? i never have. i've thought and fantasized about it a lot though. As a total bottom gay guy with a sub nature, my rectum is my primary sex organ and has been as far back as i can remember. i learned how to hide all of that from an early age, so none of those attributes seem readily apparent to others?
i'd love to have a Mate or FWB who is my opposite, Total Top with a Dom nature, but subtle vs overt. For me, suppositories are part of a category of control and when i imagine them being used with me it's either done without my knowing on the one hand, or in a matter of fact way on the other.
In the first way, without my knowledge, i'd be used to Him penetrating me all the time as part of a natural dynamic between us, so i imagine Him sneaking suppositories into me when the urge strikes Him and me not seeing them and just assuming they were some type lube. The arousal and connection for me comes from when things start to move and He is aware why, and i am not, so i'm particularly vulnerable and He is aware and in control of a bodily function that has a lot of potential for embarrassment and humiliation, and He'd be there to be assuring, not surprised, in full control when i am not. i guess a lot of it has to do with possessing and control for me?
The second way would be an assumed dynamic where He naturally assumes open control of such things with me, a sort of affectionate ownership, but not overtly so? A big part of the dynamic is His obvious desire/lust/need to be in that position with me. i'm responsive, my submissive nature is hidden with most people, and is never evoked by force or bullying. But there's a sort of affectionate presumption, which isn't presumption at all, when a Man really sees that secret place in me and wants and knows how to affect and control it and me. i imagine Him showing me a suppository and talking about it at length, all the things it does and why He wants to use them with me. i guess it's sort of strange because it's the opposite of the first dynamic? i imagine seeing the lust in His eyes, yet with full self control He knows He has the keys to control me, so He can be apparently solicitous, telling me what He would like to do with me, asking permission to insert suppositories into me. Asking me to stand, asking if He can remove my pants. "will you lie on the bed on your side for me?" "Is it okay if i draw this leg up?" As He softly strokes my behind and gently spreads my cheeks He asks: "is this okay?" The whole approach seems like He is asking and giving me control but He knows that by doing so He has full control as He slides suppositories in one by one, asking each time if it's okay, asking if He can do another, Him wanting to see how many i can take.
