Can a female ever be charged with sexual assault under This law?

Hypothetical situation:

A man is sitting on a couch when his girlfriend enters the room she sits next to him then grabs his penis through his pants. She then continues to take his pants off but not a word is said between either of them. She takes his pants off and then proceeds to fellate him. Throughout the entire ordeal no one says a word.

Hypothetical situation 2: A man wakes up after a night of partyinf to find a woman fellating his morning wood. He never says yes and she finishes him.

Since he never said yes if he decided to report it could/ more importantly would she be convicted of sexual assault?
