jbibiza: Which is never going to happen... human biology just doesn´t function in that manner... so you find people trying to get the same types of adrenaline rush from creating drama in the relationship or skipping from relationship to relationship.
I´m one that does need the chemistry in order to start something, but realize how much better it can be once you grow to truly love each other, and how much stronger that is then chemistry if troubles arise.

But Jacquie, I seem to recall "friendship chemistry" lacking in for you in one case, which led to your not starting something...
You likely meant "sexual chemistry," but if my account of what romantic chemistry consists of is correct - namely, that it is "composite" (that is, composed of many different elements) - then you did stop a relationship based on a lack of chemistry.
I think if I'm right about chemistry's composite nature, then it is impossible to sustain a romantic relationship without it.
Your comment "...trying to get the same types of adrenaline rush from creating drama in the relationship or skipping from relationship to relationship" is very (typically

) perceptive of you. I think that applies to sexual desire, however. It's very discomfiting indeed to feel the waning of sexual desire in a previously "hot" relationship. No one wants to believe their significant other is losing physical desire for them, but I think that only becomes problematic if one experiences that diminishment as a reflection of one's inherent desirability or worthiness, rather than as a likely natural evolution of a romantic relationship (please note that I wrote "diminishment" rather than "absence"

).
The sense that one has become less desirable to one's partner could easily lead to the desperate "drama-creating" or "adrenaline rush seeking" behavior that is so commonplace: frightened men and women endlessly chasing a romantic high in order to feed their sense of self-worth.
I've certainly felt some of that anxiety myself - especially since I've so rarely experienced an intense sexual chemistry. I am a little afraid of losing its erotic fruits too soon, but I'm hopeful that I'll be able to appreciate the deeper rewards of a loving relationship as they come to fruition...
