Funny. Sweet. Honest. Mature. Raw. Charming. Intriguing.
Real (not realistic, if you get the diff).
Sexual, but not manufactured or obscene or dirty, but kind of wistful, nostalgic, romantic...
It's a story about sex and sexual discovery, not titillation and arousal, a character story, foremost.
It's pretty great (honestly one of the best comics I've read this year even), and currently free on Comixology, so you have no excuse, unless you like to keep that stuff all repressed and stuffed in, then it may not be your bag.
