i agree with cindy, the first couple of months are a time period that you will go through a significant amount of emotional changes, your sex drive will come back but it will be very different, it won't be so persistent but it ramps up very quickly when activated and it will peak very high,
also know that your on hrt your hormones are normalizing and your body is finally feeling better now that the hormones are bringing you to a state of chemical balance, it will feel like you don't need them but as soon as you stop you will have the old feelings come back again,
the one thing that you need to look out for is depression, i struggled with that myself and as soon as i changed my anti androgen the depression went away, some meds just don't work well with some people, you need to give that input to your endo because they will be able to try another medication if your having problems
best of luck
