An idea which occurred to me:<br/><br/>Kelcis said specifically that he likes the sound of human female voices. Rrptile hearing is interesting.  Very very sensitive, very acute - but not very directional, they can't establish a target's/threat's bearing very well by sound alone the way mammal's can.<br/><br/>The hearing sensitivity shades into their perception of vibrations through the ground.  Research is rather limited, but there is evidence - very sparse - that reptile brains just process sound inputs differently from mammals.<br/><br/>In short, perhaps Kelcis<strong>really</strong>likes the sound of a female voice especially a voice that is expressing sexual pleasure -  it wouldn't surprise me if Kelcis can hear noises a woman doesn't even know she's making -  and the physical tremors that sweep through a woman's body during sexual excitement and release just feed into that.
