So, I'm a trans boy, I'm 27 and I've been on HRT since I was 15 years old so my experience with estrogen as a dominant sex hormone during adulthood/past puberty is pretty limited. I had top surgery in 2010, I'm having bottom surgery this year. My entire life, including prior to transition and during transition, I have developmentally not met puberty/sex-related characteristics for my birth assignment.
I have had my chromosomes tested (I am XX), but beyond that have not really had much in the way of examination done on my organs, internal or external, and part of that is actually DUE to some of the concerns I have. I do have a vaginal opening, but it is SMALL. I have attempted to have a gynocological exam in the past, but the doctor could not even get a good look even using a speculum sized for an actual infant. She was able to insert a swab to do a PAP test, but she was kind of reaching blindly. I do have a uterus but it is extremely close to the entrance based on what she was feeling and tilted, so the opening is small and it is shallow inside. I have never been able to have any kind of penetrative sex with it.
I hit puberty at age 8, I started menstruating, I got a lot of body hair, my voice deepened, I became broader. I did have some breast growth but very small (small A cup, I never wore a bra prior to when I started binding). My hips remained narrow, I didn't really ever experience any fat distribution in the typical areas (hips, bottom, breasts, etc.) It was really distressing, not because I had a particular issue with anything that was happening to me (though the bleeding I could've lived without) but because everyone reacted to it so poorly and made me feel so horrible and ugly about it. People would argue with me about whether or not I was "really a girl" in school. When I had my hormone levels tested prior to starting testosterone at age 15 I was not told that there was anything abnormal about them, but I don't see how that can be the case given what puberty was like for me.
My transition experience was extremely easy. Like easy enough that I have trouble relating to other trans guys. I have always passed. I'm extremely grateful, but it has been sort of isolating in that I do not share experiences with either cis men or trans men, and I have to reach blindly to find my way about medical care as so much of it cannot or does not apply to me. I am concerned about my upcoming surgery and how my very small vaginal canal might make some things like hysterectomy more difficult. My urethra is also located at the base of my clitoris/penis, rather than above the opening to the vagina as is more typical. Will this affect my urethral lengthening procedure? I have very good growth (right around 3"), but not very much labial tissue and I am concerned about how that will translate into the materials needed for surgery (scrotoplasty, urethral lengthening again...)
Has ANYONE here experienced any of this and do you have anything that you can offer me to guide me when moving forward, or is there anything I can ask a doctor to look for specifically if I were to ask about it? I peripherally worry about things like cancer, as my grandfather died of prostate cancer. Is that something I need to worry about? Do I have parts that could be subject to those concerns? Thanks and sorry for the text wall, it's just somethign that has been on my mind more frequently as I get nearer to bottom surgery.
