Why men always care about themselves when doing ?

I feel so frustrated. I m 26 now and i still don t know how its to be loved with pion and not just f___ed or used during the ! The men with who i have a relation(sometimes long almost 3 years) always care only about their pleasures when we are having .They never wonder if i m satisfied or not and i don t want to tell them what i want...i don t think this is the way...I know what men like and i enjoy to pleasure him without to be asked.I think this thinks come from their nature not by asking.If i have to ask i won t enjoy because i know he is doing something what he don t want...I don t know why its always like this...i think i m a beautiful and sensual woman,but..somehow i always get lousy men. :(
