So from a very personal standpoint, I argue that sexual preference is not a choice. I believe that sexual preference is very fluid, in the sense that it could include a preference in gender (i.e. homosexuality), but even within heterosexual couples fluid sexual preference still exists, simply by recognizing what turns you on, may not -- in fact, most likely will not -- be what turns another heterosexual couple on. This is preference. Preference does not equal choice.

Sure we may have a choice to ignore our preferences, but I do not think that we have the choice to genuinely prefer otherwise. I don’t feel that a man who claims to be fully heterosexual could choose to kiss another man, and it also be his preference. I am venturing to guess it would not feel natural and furthermore may even disgust him. So why is it that people assume that a homosexual person could choose other than what feels natural to them, or put them in a position where they feel as if morally they should have to?
Which brings me to my next point: I do not want to know, or think of, or imagine what you (heterosexual or homosexual) do in your bedroom, or wherever else you may have sex . . . no offense. I do not even mean just whoever is reading this, specifically, I mean anyone. Sex is so intimate and so personal between the people having sex. The fact that it is even up for deliberation what people may (or may not) be doing behind closed doors, which are consensual acts between adults, is beyond me. Homosexual couples acting on their sexual desires do not hurt anyone. It does not affect anyone. People do not look at a heterosexual human and immediately associate them to who they are having sex with and then judge them according to that basis.
