ate my cake 

Two people who likes each another decide to have sex and there forth there's not longer a relationship , due that fact.

also: after hook up symdrome, when you realize wasnt a good idea for you to have sex, because you really liked the person.

I feel so sorry,I had sex with this person i really like and I guess I ate my cake before the weeding, won't txt, talk to me anymore...

Had my cake and ate it too 

The act of cumming inside of your lady and then proceeding to give her oral sex.

Bill: Can I have the room for sex?
Jon: Sure! Don't worry, I already had my cake and ate it too.
