Okey dokey. Let's assume for a minute that you're going to read for this guy. Even though we don't think it will be accurate. I've had an idea. Just please remember, treat it as fun, and not necessarily the absolute truth.
Separate the court cards out of your deck. You won't be needing the ace-ten or the majors.
Choose a suit to represent that he's gay/bi. I'd choose swords, but wands would be just as good. Shuffle all the court cards and draw one to represent this fellow.
I'd interpret something like this ...
Any suit but the one you chose means he's not gay/bi.
A sword (or wands if you prefer them) means he's gay or bi.
If you pulled a page, he's new to being gay. Perhaps he just came out of the closet, or is in the process of coming to terms with his orientation.
A knight means he's active in the lifestyle. Perhaps into parties, bars, "the scene". Maybe even kinky.
A queen or king means he's a more mature person, interested in a more serious relationship, rather than just a sexual encounter. If a queen, well, he's a queen. Inclined to be the flouncy one. If a king, he's inclined to be the more masculine partner.
I'd treat such a reading as fun, but I wouldn't base my life choices on it. It could be used as an ice breaker, though. "Hi there, a friend tells me you're the queen of wands ..."
