So here's the question i have a friend who is currently in the military, He got engaged to his HS sweetheart before joining up. He was sent over seas for a year, He confided in me that before he left his gf wasn't very good at preforming oral sex and now that he is back she does it like a pro. He asked if I thought she was cheating or if there was another reason she has gotten better. Anyway I don't want to give him the wrong advice. And ruin his relationship. Personally I think she is cheating but my wife says otherwise, that maybe she watched porn ect. Anyway I would like to know what other women think. And if you taught yourselves. Thank you.
