People that online date- do you find it difficult to feel that “spark/chemistry” when it’s someone you’ve met online vs organically?

I seem to be able to be feel an emotional attraction to someone quite quickly when I’ve met them organically say at a function, mutual friend group or whatnot. But I’ve probably met over 30 guys here and there in the the times I’ve been single over the last few years, and all of them – nothing. Anyone I’ve ever dated, had a crush on, felt an emotional attraction to – has been someone I’ve met in person first.
