I think that there should be a very clear difference between a 'Homosexual Act' and 'Being a Homosexual'
I believe that one can engage in a "Homosexual Act" and still be heterosexual
* Homosexual Act - Noun - any bodily contact between members of the same sex for the purpose of satisfying sexual desires, whether actively undertaken or passively permitted
As a
sexual orientation, homosexuality refers to "having sexual and romantic attraction primarily or exclusively to members of ones own sex"; "it also refers to an individuals sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them.
So the mutual jack-off is a homosexual act but does not necessarily mean that those engaging in the activity can be deemed 'homosexual' unless they are drawn exclusively to the same sex, on a regular basis and it also relates to their social and personal identity.
I am gay, and frankly wish more heterosexual men would allow me to suck their cock. I am not engaging in the activity with them because of my social or personal identity, I pursue the opportunity, because of the specific act of enjoying a penis of size in my mouth. Basically, yes, I might be pleasing him and giving him attention...but I am not really thinking about him in a romantic way...I, myself, tend to be in a bit of a trance and focus my energies in getting "lost" in the act of giving intense head.
