text: how old? do i have to be a certain age to....? ok i have a couple of questions. these are just questions that are results of conversations me and my friends had....dont tell me what to do and not to do.... just give me answers please.  do you have to be a certain age to buy condoms and if so, how old?  how old do you think is the right age to have sex?  how old do you have to be to buy birth control?  how old do you have to be to buy a pregnancy test?  i know what you all thinking ;-) but me and my friends can get pretty weird and these are just questions that came up during conversations. i'm not going to go do something stupid orget pregnant. just answer the questions please? no they are very fair questions. condom there's no age limit for these. as for the age to have sex, that varies from person to person, if you have to ask then you are not ready. you will know when the time is right. by birth control i take it you mean the pill, once again no real age limit but it's up to your doctor, as this is a controlled drug. once again no age limit on buying a pregnancy test.
