I might have a wierd kink
What sort of kink are you talking about?
I mean that I want to have sex with an overweight girl.
Hey, what ever floats your boat. It is okay to have desires about things like that.
I don't want to do it. I just wanted to prove that some people have fucked up desires.
Well whatever your reason, as long as you aren't hurting anyone then it's fine to sleep with whomever you find attractive.
