sad night

just started seeing this older guy for a few weeks now, hes in his thirties and really into ddlg stuff. tonight he came over and we got super intimate quick, i mean like really rough and explicit domination right away. hadnt done anything like that before so it was intense but also kinda freeing at first. after though he started talking about how i should just do what im told without question and act all submissive in public too even. it felt weird leaving his place thinking ill have to walk around campus looking and acting like some little puppy dog for him. not sure if this is real for me long term or just a quick thing.
