My marriage has been pretty much sexless/ low physical for the last five years but last night my wife got me to do cunnilingus for her. Maybe she is warming. She had a problematic vagina so sex was painful before giving birth but maybe the traumatic virginal birth fixed it a bit. She is anti-mess person so having low mess virginal lube (one that doesn't mess up the sheets) is the best one for her. Which is best for that?
