My personal experience is that to express femininity, whether by clothes or makeup, or whatever means is a sensual experience. Sensuality definitely adds to sexuality.
Earlier in life, when hampered by fear, self doubt and lack of confidence, or other restrictions like time, the duration of my experimentation with expression tended to be brief, and also tended toward the sexual. In that context, I believe the drive for sexual relief may be influenced by the need for an instant strong emotional synthesis of the experience.
Once I had the luxury of being able to take my time, and finding more confidence in my presentation, the sensuality remained, but the sexuality that used to accompany it, started drifting more into the background. It can occasionally still rear its head, but has definitely lost its urgency.
