You said the choice of one's sexual partner matters because it determines their sexual preference. Why does someone's sexual preference matter?
Clearly it matters or else we would not even be having this discussion, i.e. if everyone were heterosexual, there would be no need for a discussion of this issue as it wouldn't exist.
Bistiza, you're an idiot, so it doesn't surprise me that you don't know what the word "preference" means, but I'll just check the dictionary for you:
dahs, you seem somewhat intelligent until you start with the personal attacks, and then you seem like a petulant child.
"That which one prefers." Not "That which one chooses."
You choose who you prefer to be with. No one forces anyone else (under normal circumstances) to be with anyone in particular, either romantically and/or sexually. You're in control of who you are with in those ways, and clearly those choices indicate who you prefer to be with at that time.
Sexual preference is not a choice. Who you choose to have sex with is a choice. But not sexual preference.
Sure, you could prefer to have sex with someone else, but that is irrelevant compared with what you actually do.
I wish you'd respond to the questions about having sex with men... If it's a choice, you could do that, right? Just flip the switch in your head and change to a homosexual preference. Right?
If I wanted to do so, yes, I could.
There's no reason anyone can't do so if they want to do so. It's simply a matter of what you want to do - everyone has their own reasons for choosing what they do, and anyone could change at any time. It's up to each person to choose.
