A stranger on the internet here, but.. I don't think you're a wuss, honestly, I don't think people our age range should be reading stuff like that. (But then again, this is the internet, and people pretty much do whatever they want.)
You aren't letting anyone down for not following what's considered "trendy" or "all the rage". You should stick to what's comfortable for you, not what's comfortable for anyone else.
At the same time though, don't be afraid to try new things! As long as they don't make you uncomfortable.
(Oh, and, if possible, maybe tell them not to mention Smut around you. :])
