This is so freaking weird

Last night I had sex in my dream (not to my husband mind you ) and had an orgasm twice.... I never picture myself or think about cheating on him which is why this dreams has me worried....but I wanted to know did anyone else experience this (especially the orgasm part) from a dream.... I mean I seriously woke up and my vagina felt sore and everything.... isn't this something young boys go through in their puberty stage not women entering their 30's
