Why not just use Yuri instead of shoujo ai? Btw, shoujo ai makes it sound like pedophilia. It means "girl love", but not in the sense of love between girls. It sounds more like "loving girls" or "(someone's) love of/for girls". The problem is that it's using the word shoujo, which stands for underage girls (10-18)... So having a shoujo ai tag is like having a tag about loving underage girls, which can easily be pedophilia ._.
