I always had it, it just became more noticeable to me after transitioning. Taking hormones (and especially testosterone blockers) totally kills your sex drive (which makes sense, testosterone was my primary hormone for controlling my sex drive before). Ever since then the separation between my bodily sex drive and my mental sex drive became very apparent. Having no bodily sex drive anymore killed my desire for masturbation, as there is pretty much no need for it. My mental sex drive however still stayed strong, which made it obvious that this is more than just a natural sex drive. I yearn hard for any sexual interaction. I sometimes even feel like I’m going crazy over it. It’s like my bodily sex drive fully went into my mental one
I did notice a lot of changes through HRT. My skin is wayyyyy more sensitive to touch. Also to pain. I was always very ticklish, so it’s hard to notice a difference there. My skin chafes very easily now, which can become an issue when walking because I have big enough thighs that they rub against each other. Interestingly I can receive a lot of pleasure through vibrations now. Before I was kinda “meh” when it came to that because I didn’t feel much. Now I bought a vibrating wand and the amount of pleasure from that is insane, best 80€ I ever spent. There’s probably more that I am forgetting right now
I transitioned socially when I was 20, so 3 years ago. I started hormones a year ago.
I think that what you’re describing is a relatively common thing, especially with people that have a higher sex drive. To me, some of that is also a bit more extreme. As I said, when I went on testosterone blockers I didn’t feel a need to masturbate anymore. At the time I wasn’t really sexually active, so I didn’t have any sexual activity going on for month when I started to notice me getting really horny. I thought nothing of it. But the next days it just go stronger. After 4 days, I was so horny that I felt drunk. My vision got blurry and I couldn’t walk straight. My friends thought I was abusing drugs and I somehow had to explain to them that, no, I’m just that horny. I tried masturbating at that time, but it didn’t help. It only went away once I had sex on day 6. Since then I rarely ever go a week without sex.
Now, for most people, testosterone will be the primary cause for their sex drive. But for me it’s all a lot more mental than that. I can’t really say if high sex drives taper off naturally. Maybe they do with age but I can’t really give an answer to that
