Hello, ladies! I've been "struggling" with my gender identity for some time now, and while my therapist believes I might be more fulfilled as a girl, I'm starting to feel more and more conflicted – mostly in making sure I'm wanting to transition for the right reasons, and creating reasonable expectations. I was hoping that by getting advice from those who've been through this, I would have a better idea where I fit. I was also hoping that this wouldn't turn into a symptom dump, but that seems inevitable :p
Some background info: I'm an only child, so cross-dressing was never something that crossed my mind (especially since I haven't thought about my gender until recent years, but more on that later). As a kid, I always gravitated toward "cute" instead of "cool". I never played with strictly female toys, but I had way more stuffed animals (essentially dolls) than action figures. I've had depression/social anxiety/self-esteem problems since I was 16 (I'm now 20), and I've felt I'd rather be a girl for at least the past couple years. I never looked into transsexualism until recently because that's pretty taboo in my small hometown, but I'm an adult, and it's time to start making my own decisions regardless of what people think.
I've always been bisexual, but, again, it's just not something I thought about until I was older. Some of my earliest memories are....uhhhh...."thinking" about boys from school. These thoughts receded as I gained awareness, but have come back as strong as ever and are constantly getting more and more prominent. Nowadays, I find myself being less and less interested in having serious relationships with girls. I still find them desirable, but I'm never sure if I'd rather be them or be with them. Sometimes, I feel like I want both XD I should probably point out now that I've never been in a relationship, nor am I sexually active.
I feel I'd rather be a girl because:
I'm infatuated with the thought of taking care of and styling my hair, wearing makeup and perfume, and dressing in female clothing. Being a boy is bland, and I've always felt like I can't fully express myself the way I want. Clothes shopping is just depressing when I always end up staring at girl's outfits with complete envy.
I have an easier time getting along with girls than guys, so I kind of feel like being female would expand my social life. Maybe because I could better express myself and talk about the topics I have more interest in.
I have almost no masculine interests. I play video games, but I can only get fully immersed if I'm playing a female character. I play guitar and drums, but I also sing and play keyboard which are more typically associated as being feminine. The only sports that don't detest me are soccer and tennis, though I'm good at neither. I seriously can't think of any large ways I express myself as male, besides the fact that all of my friends are guys so I get forced into discussing things I just don't care for,
I'm excited by the idea of being on hormones and feeling more intense emotions. It's been too long since I've cried to a good story, and I just don't feel as connected to other people as I feel I should.
I love the female voice. Like, seriously, I could fall asleep to how soothing it is, and most transgendered people that I've followed online sound perfect. Nearly all of my idols are female singers. I would LOVE to speak with a sound that beautiful, no matter how much training it would take.
Whenever I try to act "male" (everything from lifting weights and walking with a hunched posture to speaking low and grasping things like an ape), I feel like I'm faking. I can't explain it better than saying it just doesn't feel right.
As I maybe kinda sorta said before, I get really jealous of other girls. Instead of looking at a gorgeous girl and feeling sexual thoughts like all of my friends, I fixate on how much I'd rather have her hair, eyes, face, hips, etc. I find girls attractive as potential mates, but that's almost never the primary thought in my mind.
Reasons I'm conflicted:
Appearance is probably one of the biggest thoughts involved. I always get told that I look young for my age (my friends unanimously agreed I look 15), but even smaller than average hands and feet are considered quite large for females. When I think too hard about how I'd rather have a female appearance, I get worried that I'm just being vain because I find women more attractive.
I don't have a severe case of body dysphoria. I don't despise my penis, but I would prefer if it wasn't there. However, when I noticed my first chest hair growing in a few weeks ago, I nearly spazzed as that's simply putting me down a direction I don't want to see myself in. Also, the thought of one day losing my hair has made me genuinely paranoid, especially since MPB is dominant in my family.
I've never seriously considered being a "woman" – only living my life as a "girl". I'm still unsure how I feel about one day being an old lady (and I imagine most cis girls feel the same way), but I do absolutely know that I don't want to be a man. Being a feminine boy is kind of alright, but being a man, a resounding "no". Genderqueer/androgynous just isn't something I take enough comfort in to spend heavy thought on.
It's very possible that my transition could go poorly, making me unpassable or an unattractive woman, and this worries me. FFS/SRS likely won't be options until a few years after I graduate from college. Is it normal to be concerned about this when I don't have heavy dysphoria in the nether regions?
I'm worried that all of this is just too perfect in my head. It entirely explains all the feelings I've had toward myself, and I do tend to be a slight hypochondriac. As another posted said, what we want in fantasy may not be what we want in reality.
I'm sure there are plenty more thoughts I can list, but this has probably gone on long enough. I'm sorry if any of this is confusing, but that totally reflects how I'm feeling inside

Any advice, comments, or experiences are greatly appreciated as I wade through this hazy plain of perception.
TL;DR: I'm either a very girly boy or a slight tomboy, and I'm unsure which path is right for me.
