My sex drive has gotten more intense and more easily satisfied since I started taking testosterone. I also get turned on by the slightest thing (and sometimes really quite weird or awkward non-sexual things too).
Before my sex drive was more lingering and I often didn't even know if I was horny or not until I "found out". It was a lot easier for me to reach multiple orgams before T as well, but it's still possible for me to reach occasionally. But other than that I don't think more things have changed about my sex drive. Not due to taking T at least. My frequency of masturbating hasn't really increased though, it's still once/twice a day since I was 9.
Yes, taking T has increased the size of my clit. Not by a huge amount, I admit, but still. It was about 0,5 cm (0,2 inch) before T and then grew to about 2,5 cm (1 inch) and I doubt it will grow more now as I haven't noticed any more such changes for the past 2-ish years now. (Been on T for 4,5 years). Mine does look and feel very similar to a penis, but yeah albeit a very small one. I like it regardless, though.
It was kind of uncomfortable in the beginning of it growing due to clothes chafing against the tip of it extending further and not being protected by the labia anymore. But eventually I didn't notice the chafing much. I still do sometimes but not enough for it to bother me.
