Maybe something along the lines of "My mom says I'm special" (and maybe add to that: "and mothers never lie"/ "and she never lies") and add a cheecky smiley ;)

Just make up some dumb "reasons"

"I'm an amazing cuddler, I'm great at karaoke, and I make the best ramen noodles 😄"

I'm the one who is gonna make you cum. You're welcome brother.
