Does any one else like feeling their own body?
I think it's rather normal especially after a workout to feel, be captivated, even sensually, by the results of one's labors.
Just like you when I'm in the shower after a workout, running my hands over my nude body, I'm much more aware of the sensation. It's more of an objectification of my own body as my hands are my lover's hands and I'm getting a sense of what he'll be feeling and of how his hands will feel on me. Can be arousing at times especially when your body is changing and the sensation is new and oddly unfamiliar. As if you're touching a stranger's body.
I'm currently into my post holidays winter workout to prepare, as I do every year, my body to rock a bikini come summer. When I get my ass, stomach, etc., to peak tone and firmness it's hard not to take pride and view oneself as a desired sexual being.
I'll examine my naked form in the mirror caressing aspects of my body and have that, "I'd fuck me" moment. Narcissistic? Partly. But we all have that level of ego that, in this instance, drives us in a positive way and makes us a healthier and more confident person. As long as your ego doesn't become too inflated, that you don't become too infatuated with yourself, confidence, an awareness of one's own sex appeal, is healthy and perfectly natural.
