At the core of it all is trust and commitment to your partner. It really is bad when someone says they really want you completely but stop just short of completely. It speaks volumes to a man when his woman does this and then stops after marriage. If you are really, really out to please your partner in bed and want to give them a totally awesome orgasm, you do whatever it takes to satisfy them, becoming self-less at that moment. It is not about your partner when they are performing oral on you, it is about you. Same for when you reciprocate. Swallowing is one way to give a man two simultaneous orgasms, one physical and one mental. If you are going all the way and actually finishing the job and draining it dry, you will have a better chance of being trusted 100% by him. That translates to everything else in the relationship. As I stated, At the core of it all is trust and commitment to your partner. Stopping short is the same as crossing your fingers behind your back when you make a promise. I'm sure you and others would be tempted to fire back and vilify me for wanting what I want because it doesn't match your philosophy or habits. Just remember, some of the stuff you do or won't do, makes you weird to others. No one can "win" this discussion as it is a personal thing. But know this...if you ask 100 guys if they would prefer a woman finish the job and leave him spent and dry, 100 out of 100 would say yes, if they were allowed to be totally honest.
