My boyfriend is very dominant and we both enjoy this dynamic. We try all kinds of sex positions and they all feel wonderful. Sometimes as foreplay ill give him oral to get it all reved up and do some teasing while i do. Sometimes when we are doing penetration he finishes before i do. Id like to start continuing with other things so i can get off too ( im on meds that make it hard for me to orgasm so it takes a lot) we can't find a position for him to give me oral that’s comfortable for us both so i was wondering if facesitting would be out of the question for a man that likes to keep in control. How do i even sit up there? How do i “prep” for it?
