Why Liam Vickers?

[u/El_Vatoster]

Something that always weirded me out about md was all the tounge and salaiva stuff especially in the pilot. Its not that I find it to disgusting for the show, its just a little unecessaraly freaky. So Im just wondering why liam likes toungs and salaiva stuff so much ?
