Thanks for all the welcome's...
Buryuntime, the social story was supposed to tell you not to rearrange your own junk in public, but it instead of/as well as showed an aspie telling a girl not to rearrange HER junk in public. I don't know if you've ever made a comment about someone's bra or what she's doing with it in public before, but generally the reception is not a chirpy "thank you".
I've actually started making my own social stories, in comic form (that's how my daughter likes things, lol). Alas, I cannot post links here yet... apparently I have to make X number of posts before I can post a link. I will assure you, however, that in MY version, the kid is clearly scratching his junk, and not his pants, lol.
That book looks cool. I've always been painfully blunt with Eowyn about sex, not sure if this will cover any new territory for her... her last question regarding sexuality was about whether or not people risk getting stuck together if they engage in anal sex... and, beet red, I answered it. I thought I was going to have a heart attack, but I answered it, lol.
