It's an interesting thing to fantasize about. I personally have found having a ball sack to be "sticky" and somewhat uncomfortable. It also makes you vulnerable down there
. I think a (circumcised) penis can be beautiful. Vaginas have their "gross" aspects too. It makes you wonder why God the Creator made us this way. We, being human, are too infantile in our thinking to possibly understand why such things are the way they are. I also don't like having facial hair, but that's another subject.
When you as an Infinite Soul incarnate in a human body, you (we) are taking on limitation. Humans are "Masters of Limitation". But our bodies allow us to interact with the physical world in a very direct, "earthy" way. There's a reason we're here--now--in our present form. Our bodies are very important to us, because that's all we have right now. We want to experience pleasure and avoid unnecessary pain.
In our true, eternal, disembodied state, our spiritual bodies (our True Selves) are, I believe, highly glorified and most purely represent our True Essence. They are also changeable at will, because we have access to all knowledge, power, and beauty. The pure soul may express itself as male, female, or both. The images below may suggest how you or I might truly appear in the disembodied state in the cosmic 4th and 5th dimensions. In the second image (brunette) my eyes and eyebrows are a good match; and when I was 3 years old my mouth and lips looked just like that . . .
