*shakes head slowly* No, we're not.
I am straight. I get turned on by women I see as attractive. There are guys who I see as attractive, but they don't turn me on.
Now, if my fiancée offered me a threesome with another woman in exchange for her getting a threesome with another guy, then I would definitely engage in some sexual acts with a dude I thought was attractive enough (not as far as penetration, though). But I wouldn't be turned on by it, and I wouldn't do it for my or his pleasure. I'd be doing it because I know it would excite my fiancée and would make her more inclined to engage in similar activities
I find exciting once the threesome with another woman happened.
But here's what I thought was really stupid in OT:

To put it simply, no matter who you are, any kind of sexual activity can and will get you off, even if your too shy to admit it,
You know what can constitute as sexual activity? Being hog-tied, getting scalding hot waxed dripped on your naked chest, having your nipples hooked to a car battery via alligator clamps, getting a glowing hot iron rod shoved up your ass, and getting your dick/clitoris cut off and eaten. I kid you not, these are things that can and do turn people on [http://www.urbandictionary.com/define.php?term=rule+36]. I'm pretty sure my revulsion at the thought of those activities doesn't stem from me being "too shy."
My captcha is "get out." I think it's talking to you, OP. Get your head out of the clouds and do some research on Rule 34 and 36 before making this kind of statement.
