Going back in my mind and thinking about a lot of the men I have been with are in it for themself. They want a complete, cum sucking blowjob. Liked me suck them off so they can split. They may suck you a little but only a few made me cum because they were enjoying doing it. Then again I had one friend that loved me to suck his cock. He told me that he would not return the favor but he loved getting complete blowjobs. He had a cock that I really enjoyed sucking. He would watch me jack off after. But that was it.
This was not everyone. Had a few that like to swallow or finished me off by hand. Just did not like being left fustrated
