Hatred of that part was my first sign of dysphoria at age 4. Back then I didn't understand its use as a sexual organ or even that biological girls didn't have one but because it was referred to as a "private part" and not shown, I assumed that everyone was ashamed of that part of the body. This is why I feel my dysphoria was intrinsic, as even with very little societal influence and no knowledge of what a vagina was, I still wanted to get rid of it.
Like many, the dysphoria for that part got worse during transition, and even though I wanted to, I could never date or fathom having any kind of sexual intimacy. However after my SRS surgery, I remember the moment that I woke from the anaesthetic so vividly, I immediately felt that lightness between my legs (despite all thof bandaging) and it felt as natural and precisely as I had dreamed of. Before the surgery I had warned myself that perhaps it would not be as I expected, but it was precisely as I had expected and known all my life for 23 years at that time. When I saw it with my eyes, it wasn't so much euphoria, but more like "yes, this looks normal and right" although even now, seven years later, I feel so grateful for it, and certainly worth the 5 year delay when I thought it would never happen!
