No doubt guys, its all about timing. Can't rush into it to early. It also helps if you explain yourself in a non perverted manner. i know with my ex any time we went jogging i'd want to smell her feet afterwards.
it took her time to accept it...but once she did...it was bliss
"omg i so tired...that was a good run. Lets hit the sh0wer baby. oh wait, you wanna smell my stinky feet don't you?"
"yes honey"
