lol i never understood why its so hard to say something so simple so plainly.
To Xirius: Put a condom on, go out and find a girl (or guy...or dog...or blow up doll, whatever), screw yours and her(his? its?) brains out. The go to sleep and stop worrying so much about what is a sin or not.
REMEMBER, as a Christian you can sin your entire life, repent on your deathbed, and your acceptance into heaven is still guarenteed!
