So you observed, suddenly your partner started giving you Australian Kiss without you asking then trust me it is not what you think. There must be something going inside his evil Mind.
As a man, i can say we we prefer to get B job rather than going down on our Partner ( yes you can call us selfish ) but yes this does not implies to every other Male but majority of the male community can agree to me.
IF you notice your partner suddenly giving you Australian Kiss without your asking then these could be the reasons.
Another reasons would be he is doubting you. He is worried about your handsome male friend you are hanging out with these days and he want to keep you to himself by making you realize that no other man can keep you as happy as he can.
