What do you think is more important in understanding you sexuality?

It's astounding exactly how much control our mind actually does have over us. Milton Erickson, MD once cut arterial bleeding to a trickle on his son (after a farming accident) using hypnosis. There are cases on record of people with DID (multiple personalities) where one personality had insulin-dependent diabetes and another personality did not. And there's a growing and very credible collection of research indicating that certain diseases (Crohn's, arthritis, ALS, fibromyalgia, chronic fatigue) are dramatically impacted, if not outright caused, by emotional/psychological factors.

We know that orgasm and ejaculation are directly affected by emotional and psychological state, and so it's not much of a jump from there to infer that attraction is similarly affected.

 

Avoid placing external (cultural, religious, or social) limitations on what your sexuality should be. Unfortunately, those limitations are already present before most people reach puberty, so they have to unlearn those restrictions that tell them how they should behave. I think the first step is to just be exposed to the idea of alternative sexualities (relative to heterosexuality), and the next step is to see if something fits with the subconscious desires that may be repressed or just completely overlooked.
