I'm going to do the Pagan Alphabet thingy because it'll get me back in the swing and also because what's happening in magic and witchery right now is that some stuff is settling in after some fast growth. I'm not quite sure what all I'm allowed to talk about, so I'm keeping my mouth shut.
I don't put much stock in the wonder working, lust inciting powers of oysters or sushi unless they're being served on a naked human platter. I do believe that adding textural and sensory varieties that please the tongue and the senses can heighten a romantic evening and draw the mind to other pleasures. Kitchen witchery can be very fun to play with, and I've had good success with enchanting dinner to get what I want afterwards. A certain orange and spice cake comes to mind... If you're interested in pursuing those routes and ramping them up magically, might I suggest Miller's excellent book, The Magical and Ritual Use of Aphrodisiacs.
Ritual is one of the key elements of seductive workings, particularly when what you're doing is part of keeping a long-term relationship steamy. There's huge power, psychological, psychic, and magic, in orchestrating events, actions, and sensory cues. It builds pathways you can tap into, both in the brain and in energy flow. I think rituals of desire and seduction are where it's at. Humans are easy to train and condition if it's done thoughtfully and consistently. We do it all the time in friendships, romantic relationships, partnerships, families. There are rewards for doing what people want you to do and consequences for stuff like not doing your chores. We form strong associations around sensory input, particularly when the result is an extreme (pleasure, suffering, anger, joy).
If you devise a ritual wherein you bathe with specific products or put on a certain perfume, meditate and get your intentions and energy all lined up and thrumming around you, then do the initiation on seducing your partner, you've built a powerful chain. Maybe it's a piece of clothing or jewelry. With action or scent or sensory ritual, you're conditioning yourself toward a certain head space and conditioning your partner toward associating a specific scent with feeling desired and sexy, then you reward the both of you with pleasure. It should go without saying that one would enchant or even ritually make from scratch the specific scent or products used in this.
Associating a sensory cue with behavior works really well. It's how working and service dogs are trained to separate work time from normal dog life. A different collar or harness or dog clothes conditions the animals to have a unique set of behaviors, tasks, and commands that go with wearing the thing. We do it with work: professional attire and grooming puts people in a different mindset and they behave differently.
I like that there are psychological reasons that back up and reinforce the magic in this method. From experiments with candles and other quick and dirty methods, I find that they don't go as planned because everyone's head isn't in the game when the thing is launched. If I'm horny and snuggly and my partner is frustrated and stressed out, the lust spell candle isn't going to give one or both of us what we're after, even if it does lead to an encounter. Conditioning plus magic allows you to set the pace and do a slow burn thing if you want. You can pounce your partner or you can do it as part of date night prep for one of those nights where you can hardly wait to get home.
