ATLPRINCESS SHUT UP
YOU CANT CONTRACT AIDS THAT EASILY,WELL YOU CAN BUT IF BOTH OF THEM ARE VIRGINS AND THEY'RE WEARING CONDOMS THEY'RE OK
DON'T TRY TO GIVE THEM LIES TO NOT HAVE SEX,YOU'RE PROTESTING THE WORD OF GOD AND THEN YOU LIE ABOUT SOMETHING DUMB...THAT'S RETARDED,LET THEM DO THEIR OWN CHOICES
