I may be the wrong person to answer this but I don't feel like it is something you should hide. Most will find it interesting and actually want to see you do something! After a first date or while we're texting I'll casually say "Oh i'm flipping through some book on artifice... it's archaic as all hell and hard to read". "What's artifice/the book?" "Expert at the Card Table, some old book on gambling sleights or magic". "You do magic tricks?", "Yeah, I could show you some time if you'd like". Then I would do B'wave or something simple while we're grabbing coffee etc.
Or if I brought a lass home... I'm caught red handed. In my bedroom and office I've got 9 bricks split split bricks of Tally Hos, 6 bricks of Bicycles in various shades, and 2 bricks of Bees, a stack of fashion decks and gaff decks and a shelf of books + a roll up in my room in front of the mirror and one in my office where there is a desk that has a load of extra cards and random supplies for gaffing. So I'm just upfront about it.
I'm also guilty of using the french kiss (ONLY WHEN THERE IS PROPER CHEMISTRY) to break the intimate area boundaries a little bit and be a bit cheeky/flirty on a good vibe first date. (Not in the... rapey way that the one youtuber who wayyyy over did it, but as you would normally perform it) The only time it has back fired was after doing a steal and letting her see the deck that I did something a certain way and became fixated on that and got mad I wouldn't do it again for her.
If she can't accept you for who you are and what you like to pursue, she ain't for you my dude.
