Hi!
I was 23 when I started, weighed 145 lbs. and was 5' 7" I'm generally fairly small framed if a little stocky built due to my welsh heritage. Before HRT I ate pretty good (balanced diet, no soda, very little junk, mostly home cooked meals with little red meat and lots of olive oil, fish and chicken), but I slept crappy, but I also did some pretty regular if light exercise.
I'm currently at the 7 month mark. The first thing I noticed was the immediate mental change. Like by the end of the first week I was noticeably calmer, better rested, and while I was more fatigued from the HRT, I also felt more alive. The wider emotional range came not long after, lots of crying, lots of moodiness, sometimes crying over being happy. The next thing that I noticed was the drop in my sex drive. Pre-HRT I felt the need to uh... take care of things... probably 1-2 times a day, leaning towards two, and generally felt horny pretty often... or at least was thinking of sex very often. After starting HRT that dropped down to about 1 time a day for the first three months, and recently it's dropped even further to about once every 4 days.
I start getting breast pain/development at the 3 month mark, they've been sensitive and growing consistently ever since, although at a pretty slow rate as I have yet to fill in an a-cup yet.
Over all I've had consistent changes to just about everything. My skin has become much softer, I'm almost as soft as my girlfriend. I've also lost around 2 inches from my height and my shoulders have become significantly less wide as my arms and the muscle around there has feminized, although how much I can't say. Likewise my face has lost some eight from it giving it a much more angular tone. I've also experienced some pretty significant regrowth in hair along my hair line. Before HRT I was starting to bald with a rapidly receding hairline, that has since begun to fill back in and I feel like in a couple years even I might actually have a convincingly female hairline.
At around the 4 month mark I noticed that my eyes went from their normal weird murky blue-green-brown splotchy mess, to almost entirely pale blue. My eye sight has also changed although not measurably. Likewise I used to have a condition with a slight lazy eye, which has fixed itself a little... (i notice double vision a lot less now. Around the 5 month mark, the estrogen effectively nuked a lot of my body hair. Chest hair is mostly gone save for a few stupid highly blonde hairs, and my arms are gradually losing the hair on them as well. Leg hair doesn't seem to be much better, but shaving my legs takes probably a 1/4 as long as it did pre-HRT. The shape of my eyes has changed a little too, they look more female, have slightly longer lashes, and the shape is a bit more 'almond'. Just recently at the 7 month mark I've noticed my eyebrows have gone from stupid blonde weird things to much thinner, darker and more feminine. I also gained light freckles all across my face, and on my shoulders.
Around the 5 month mark I lost my ability to hold an erection for a short time, but it has come back since, although getting it up is a bit more difficult. Also as of the 4 month mark most of my orgasms have been female. I still have a male one occasionally, but very rarely now. I think my hip bones in general have gotten a bit wider and just my leg shape is much more feminine now.
As of the last time I weighed myself, I came in at 128 lbs.
