If you think about it, it's very probable that Tony has had sex with Jeannie's sister while he and Jeannie are married. Jeannie's sister was always disguising herself as Jeannie in order to get Tony, I'm guessing she continued this scheme after they got married..... We only see Tony's and Jeannie's married life for ONE season, and even then her sister tries to wreck their marriage.... So it seems likely she would continue throughout their marriage.... she was certainly still at it in the movies that followed.

There had to be times she got with Tony, disguised as Jeannie, and just didn't say anything more about it
