"As for bodies, I don't think she likes mine, but I can't blame her (fat bastard that I am), "
DL, I realise that there's an element of DL-stylie joking in there, but IME once the initial fancying is over and the relationship is established, the easthetics of the body in question really don't matter that much (lucky for my DP who is nurturing his Inner-Texan).
She sounds squeamish and /or fastidious. Lots of people (as M2T says) have their foibles and favourites, but kissing, sweating, oral sex and other snippets you have mentioned in the past paint a picture of someone who, if she is still in love or wants to be, may have a problem. Sexual, emotional, psychological, I wouldn't be the best person to say, but intimate contact with at least SOME bodily fluids is part and parcel of a relationship, in't it? (Oh No! Now you'll describe some ghastly bodily fluid appetite that she DOES have and blow this theory out the window!)
