Heres an idea, and Im sorry for being rude, but Dont Be A HO! Come on your 15 and have had 5 pregnancy scares? Im sure they aren't with the same man or your boyfriend, hey hunny have you heard of aids, herpes, HPV? Im sure you caught something.....Why dont you go to school and get an education? Obviously your missing something very important in your life like an IQ! Wrap it up and if the condom falls off, its not the right size. Make sure the condom is the right size for his penis and you wont have this problem, or dun dun dun...Close your legs. I know this post is old, but I couldn't resist!
