I found estrogen actually increased my horniness, but it was a very different kind of horniness than testosterone libido (which felt "wrong" to me, and which I hated so much I wondered if I was asexual or meant to be asexual).
I sort of wish it had reduced my libido, but alas. At least now my sexuality feels more right, and it's probably good that I didn't completely lose libido - my partner would probably not be happy about that.
Yeah, softer skin and breast buds started early for me. My hairline is still cursed IMO, but it's not that bad - I just don't like the way it looks and I wonder if it will ever be better.
I would say yeah, around 6 - 8 months my boobs were noticeable and probably were helping me pass around that point.
The effects vary depending on genetics, dose, route, etc. such that we do notice lots of similar patterns but with lots of variance.
I feel bad for the girls who take oral estrogen, though - I feel like it just does not feminize as well as other routes (particularly compared to injections).
