That is a horrible thought process, I make it a point to make sure my SO finishes, I should want to make her feel good and feel happy, you should focus on your partner with sex, if your only in it for yourself you could be ignoring your partners needs which can make one or the other frustrated. Again, jerking off isn't the same as have intimate relations with your partner, and again he needs to find a better way to communicate then manipulating her (you seemed to have missed it when I said it the first time)
