Well, me and my ex-girlfriend used to kiss all the time...But, whenever I would start nibbling on her neck (one day I did it as a joke and she told me it felt amazing) she has miniature "Orgasms" or something, where she shakes uncontrolably, latches onto my back, and pants...I'm just wondering, physically mentally and emotionally what causes this? I mean, she has done it to me and it was nothing near as amazing as she says. Is it a normal thing, or is it all in her head? Or could it be personal preference and likes/dislikes? Can someone explain please, I've been wondering for a while

Why does it do this...?
The erogenous zones are amazing. Behind the knees or on the belly or the neck. It depends where you have tried. Maybe she has more places, spots, like these.
For me, getting my hair cut and having the barber run the clippers up the back of my neck sends mild electric shocks all the way down my spine and ending in my genitals. Having my wife lightly run her fingers up and down my neck does the same thing. Both "shiver my timbers!"
I guess it is the nerves and this being one of several erogenous zones a person has. I do not get orgasms, but my PC muscle sure gets a work out as I feel the electricity in my penis and scrotum. I guess the answer as to why has to do with the way we're "wired" and how certain sensitive spots on the body affect our arousal when touched. For more info, refer to this link:
