Sexuality and alcohol

[student90]

(I'm extending on my previous post about alcohol blackouts)  This topic has always puzzled me.  I do know that we do not have much information on what causes sexual orientation so I'm not sure how much info I can get out of this.

Let's say if two guys get drunk together and they wind up making out and having sexual contact...does this mean that one or both are gay or bisexual males?  Can the alcohol blackout be used as an "excuse" for doing pleasuring one another and not realizing what he is doing or does the man consciously (or at least semi-consciously) know what he is doing and is enjoying it as a pleasurable act?    Because in a normal setting that straight men would consider this to be "very gay."

Any insight on this?
