Scrotoplasty and testosterone therapy are available for trans men so they're available for you too. You'll be able to restore your genitals to near their previous appearance and get your testosterone back in time if that's what you choose. It sucks but you just made an error in medical treatment, it happens to lots of people for all kind of procedures, it's not shameful or a reflection on you as a person.

Detransitioning doesn't have to mean committing to being gender conforming. Crossdressing and being feminine as a male is totally valid, I think this sub is iffy on HRT but ik even that isn't unknown. I still have long hair, shave my legs, wear women's shirts and wear makeup sometimes etc. Idk if this is exactly what you're looking for, but detransitioning/being feminine doesn't necessarily need to be an either/or, and if dating is a concern of yours there are plenty of cis girls out there who go for feminine guys.

Hey, I know it sounds cliched but it's not healthy to come at this kind of stuff from a place of self hatred. You're still very young and you have a whole life ahead of you to figure yourself out. When I was your age I felt really similarly, feeling disgusted with myself for being amab, calling myself a man and a rapist and stuff when I was just a scared kid who needed to love himself more, and it really screwed up both my gender identity and mental health in general.

Internalizing those feelings early in your life can have debilitating ripple effects. I would really suggest seeking therapy if you can and trying to make space for yourself to heal and give your feelings about your gender real consideration – not necessarily to go in the direction of transitioning, but at least to understand where they're coming from. Everyone deserves that.

I mean your dick will still work fine afaik, depends what function you're talking about? You won't have testosterone in your body unless you go on T shots, you won't be able to produce sperm or have sensation in them, but that's about it. They're just endocrine glands, it's not like they do much when you're on E + blockers anyway

Edit: Sorry, didn't realize you weren't OP. Yeah, they won't produce T but you can get that exogenously at least, for what that's worth. It's mostly cosmetic. IIRC they use silicone or something

This sounds a lot like OCD, especially if you truly don't experience any dysphoria or object-level issues with living as a man. It could be helpful to focus on figuring out whether you feel enthusiastic and positive about the idea of transitioning on its own merits or whether it's just a fixation on the question itself. I have OCD and BPD and often get really obsessed with "figuring things out" about myself that feel irrelevant later or convincing myself to try out identities the rest of my brain doesn't want to have.

I would suggest just taking it slow, thinking about the problem in the most grounded, concrete terms you can think of, and trying not to stress too much about finding an answer immediately. I hope things work out!

That does sound unusually effective for one session, but typically a lot of the initial hair loss from laser is temporary and will go away as follicles that were resting during the treatment start producing hair and some of the treated ones recover (which is why multiple sessions are required to kill them for good). I don't know if you can expect complete recovery but it will at least get a lot better within weeks to months.
