I'm not getting ENOUGHHH

So i was talking to this guy a while back and things were really heavy it was like if we were dating for a long time. although he would get mad at a lot. anyways it didn't work out but we had sex and he went so fast & it was all over so quickly . like i've had sex with girls before but this was my first time with a guy. he finished in like 5 minutes and left me hanging!! told me to put my clothes on and that was it. like 3 hours before we had sex i gave him a blow job and so i gave him two nuts in a night & he didnt even make an effort to help me outttttt. So recently we had sex for the second time just a friends with benefits thing, but we were in the car and he asked for a blowjob so i got to it but then we moved to the back and i was on top and then we were going at it and he FINISHED then told me to put my clothes on. What am i supposed to do??? I mean oh my goodness.
