There are some people on this site that have some issues with sexuality. More their own i believe than anyone elses.
FFS sex is sex people. Okay so you like girls or guys whatever, its your choice. Short of brainwashing there is no way on earth that someone else can "make" you gay or straight.
I think your a pretty poor person if you can't judge a person by their thoughts, ideals, actions and morals because they like people of the same sex.
To the straight ladies I say this:
You like guys bodies don't you? Well guess what, so do some blokes.
To the straight men I say this:
You like girls don't you? Well guess what, so do some girls.
Now everyone who is straight bear that in mind, goto your bedrooms and let your imagination run wild.
