It can be looked at another way.
Gay, as an identity.
Homosexuality, as a behavior.
Straight as an identity.
Hextrosexual as a behavior.
Many men struggle with same sex attraction (SSA) whether they identify as Straight or not.
A man can consider themselves Gay, yet be married with children.
Also, consider themselves Straight (married with kids or not) & seek out other men for sex.
The old gender definitions, donít seem to apply.
CSA can really make it difficult to figure out how we think of our sexual identity now, or would have been without the abuse
Men (or women) who sexually abuse boys (or girls) arenít generally interested in the victims future sexual identity development. They may not actually be knowledgeable on what that process is in a child. Just as a child doesn't know what a "spinal reflex" is, nor would the perp. But any such reaction from a boy, would be seen as the child is enjoying the interaction. And of course we know how that is used against us.
Here are a few of normal human reflexes that can occur during abuse, which the victim/abuser may interpret as willingness to the interaction.
Cremasteric reflex stimulation of the skin on the front and inner thigh retracts the testis on the same side.
Hypogastric reflex contraction of the muscles of the lower abdomen on stroking the skin on the inner surface of the thigh.
Bulbospongiosus reflex contraction of the bulbospongiosus muscle in response to a tap on the dorsum of the penis.
A lengthy definition of this can be found at this link, http://www.scribd.com/doc/29972790/Spinal-control-of-penile-erection
Nowhere does it discuss sexual identity as being a factor.
Anal reflex contraction of the anal sphincter on irritation of the anal skin.
Abdominal reflexes contractions of the abdominal muscles on stimulation of the abdominal skin.
