I just turned 18 and I need help

There is sometimes a misconnection between the MP and the SL viewer database. It happened to me yesterday, but on the contrary, I could access to all contents in the viewer but not on the marketplace. File a support ticket. Mine got fixed in less than 3 hours.

ETA: Sorry if this sounds obvious, but did you do it right in the viewer's preferences? 

How to change your preferences to view adult content

Even if you are 18 or older, you still need to opt in to view adult content. 

Log into Second Life, then follow these steps in the Viewer to set your maturity preferences:

1. Choose Me > Preferences (or Ctrl-P) and click the General tab.
2. Choose General, Moderate, Adult from the I want to access content rated: dropdown menu.

   

3. Click OK.

Congratulations! You may now visit any publically accessible land in Second Life, regardless of its maturity rating.

Note: If your preferences are not set to allow adult content and you attempt to enter an adult-rated parcel or region, you receive a prompt allowing you to either cancel the teleport or instantly update your access preferences to General, Moderate, Adult.

If you turned 18 and cannot change the maturity settings, file a support ticket: https://support.secondlife.com/create-case/

Try to reinstall the viewer (do a clean reinstall). Maybe your cache files are stuck. If this doesn't help, you will have to file a support case.

Do you have any idea how long it might take?

If you are lucky as I was yesterday, a few hours, the support was really fast on this one. Otherwise, that should be fixed within a day or two. Do it fast because the weekend is coming and it might delay the fix to your issue.
