Getting a climax is a two step process. First you need foreplay which if you have a companion would involved cresting and massaging you where it feels good but not in the lower regions. If you don't have a companion, you need to visualize this happening. At some point, you will feel a warm glow over your entire body. At that point you are ready to move to the lower regions and bring yourself to a climax. I haven't looked but there may be some youtube videos discussing the process for a CIS woman. As you hormone balance and body is now feminine, it's more difficult to reach a climax but it's now a whole body experience instead of a localized feeling.
