How do you stroke a giraffe’s head?

Is that what you meant?

I like metal, rock, Glukhovsky’s books and shrek (I gave up writing about sci-fi and r&m to sound more normal)

I think "Glukhovsky" just sounds like a much, much more obscure way of saying "sci-fi." And I think Shrek kind of sounds... both like something everybody likes, and like a childish thing to focus on. Like, I like Shrek, but it is a children's movie series that came out in 2001, so how about...

I like metal, rock, sci-fi literature (I'm a big fan of Glukhovsky), and (something else, maybe something more abstract, like "ordering dessert" or "the sound my cat makes when I pet it" or "comfy sweaters" or "food that's just a little bit too spicy* or something).

then...

Looking for my next ex (joke)

... nope. I understand the joke. You do not want to make a joke that takes people to a negative place. Also, this particular joke is a cliche, so it's not even funny anymore.
