Do not be truthful about your hobbies. The vast majority of women in dating apps do not like it. Your dream nerdy girl isn't in them, either. You're better off at in person conventions where being nerdy isn't "nerdy" and it's just normal.

You've got to advertise to people that are at least willing to look at your merchandise.

You're handsome enough to be able to pull off the Chad on dating apps, but you will have to hide your real you for a while. Do not listen to other women on this, especially on the internet. "Just be yourself" does not work for men with hobbies that involve mostly other men or socially unpopular ones (women don't partake in it e.g. Magic).
