I'd forgotten about toilet paper roll test, wasn't sure if it was real or not. If it is all I can say is wow, I've been worrying for nothing. Yes I've measured years ago out of curiosity, used a clothes measuring tape. First time I measured underneath then thought that couldn't be right, you can't get that part into her so then measured the top, which is what matters lol. Like you said, I to was pleasantly surprised with my girth, also with length, if the charts are correct.
