Question about bottom growth

I just started an itty bitty baby dose of T gel 2 days ago and already I am having overwhelming sensations and my shit is engorged and it’s making me nervous. I know the next step is it will hurt. From guys who have finished this step: how long does this take? When will it stop feeling So Much all the time? The only trans man I know is my ex so I don’t have someone I can ask in real life. This feels like the equivalent of having an erection for 16 straight hours and I am ready for it to chill.
