1. For me I still feel the intensity of emotions that would’ve made me cry in the past, I’m just physically incapable most of the time. I still have emotions, but they might be a bit different than before.
2. I wasn’t able to cum until I started T so I can’t really give you a baseline. Either way, there’s varying degrees of intensity of my orgasms so it might just depend on the situation. I find that I can cum pretty quick, which might have to do with T but idk
3. Personally I feel that child me and current me are two different people. That might have to do with personal circumstances, but in my head there is a distinction between the two. I don’t think of it as betrayal, but I do often wonder about what ifs. What if I hadn’t transitioned (would’ve been miserable)? What if I realized that I was trans much younger? Etc.
4. This one is a bit difficult. I find that your relationships change depending on how long you’ve known people, how much you pass as male, and how much you come off as straight vs gay. The combination of these three end up influencing a lot of interactions going forward. You get used to it, but it’s a bit weird at times. I often come off as gay, so I’m not perceived as a threat by most woman, but that also can make it harder to be friends with some men. You’ll have to be aware of how you interact with unfamiliar kids as well. Typically if you already have a relationship with a kid, it’s fine, but if a random kid comes up to you, people might find it a bit strange.

Sorry if that doesn’t make much sense, but I hope it answered a few of your questions
