I feel similar to Laura. Having my clothes taken off turns me on. it's like a dramatic revealing, and it can be hot. Of course it's also hot and a real turn on for me to remove a woman's clothes, especially unhooking a bra & sliding the straps down over the shoulders & down the arms. Unbuttoning her shirt slowly is also very hot for me. Disrobing a woman & that feeling that she is giving herself to me can be very exciting on different levels, & even stir feelings of love.
Ironically my medfet began with a doctor who would slide down my undies. or sometimes just lift & stretch the waistband to view, reach in, & touch, during annual physicals without any verbal indication as i lie on the exam table. It's the act of individuals desiring my exposure to them, whether to check and feel me professionally, or a lover desiring me for physical pleasure.
Because I am clothed and not exposed most of the time to most people makes becoming exposed all the more dramatic. Someone who wishes to expose me wishes to see &/or touch. The desire to see &/or touch me and my awareness of that is hot. If I thought my exposure to mature women would be pleasurable to them, i would be tempted to want to perform for them in some capacity. From that, i derive a lot of my fantasies.
My jockstrap fetish deals with being exposed with straps over nude buttocks, and being solely covered by a pouch that i suspect draws attention of some. It's exciting to be thought of as being looked at while wearing one. I touch myself over my jockstrap and imagine it is someone else touching me, playing with & teasing, until they eventually want to lower it and dramatically expose me, and have that met with smiles, giggles, and perhaps admiration, even if facetious, over what the overt effect the experience has on me.
