There is no right way to sext by any means. People are into different things and that's fine! Maybe a "what are you wearing, baby?" works for some, while "I want to ravage yer booty, matey" might work on others.
However, there is an obvious wrong way to sext considering it'll probably kill off any semblance of what sexy vibe there once was in one swift text message.
These sexting fails are actually hilarious, though, and if I were on the receiving end of one, it'd definitely be a moment killer, but it would make me chuckle. Hard. Pun intended.
