Question for all the parents out there

I'm 16 and maybe this is just my 16 year old mind but why don't parents talk about sex like its the plague. When I told my parents I had a boyfriend one of the first things they asked was if we've had sex. I understand that question was needed but after that they told me how I shouldn't have sex at all at this time. I believe that they should of talked about the proper protection instead and how to prevent the invevitavle. So parents why do you guys treat us like children when we're trying to handle this the mature and correct way? Any comments one this?
(PSA im not asking for you to tell me I'm too young for sex. Thank you but my parents have given me all of those lectures so save your breath and just answer my question please)
