Hormones themselves won't increase satisfaction. Mentally, you may feel better, but that's all in your head. Further down the line with continual use, your bone structure etc will start to femininze, so at that point you will look better in your clothes, so you will probably feel better then. But again that's all mental.
If you're not serious about complete transformation, don't do it. I understand wanting some aspects of your body to be more feminine, but unfortunately with hormones, it's all or nothing.
