Welcome!
I'm a face latherer too

.
Here's my method:
I wash my beard area with a liquid facial soap and rinse with the hottest water I can stand.
I don't dry my face.
I hold my brush under the tap, turned hottest (about 50°Celsius).
I shake the brush two times, loosing most of the water that the brush can't hold.
Then I swirl it on top of my soap for about 10 seconds and start painting-massaging the lather on my beard. An opaque coat of lather forms quickly.
I add a few drops of hottest tap water to the brush, and start working on the face again. I repeat with additional water if necessary. I aim for as much water in the lather as I can without it starting to run off my face.
Then I go strop the razor.
When finished, I wipe the brush along the side of the bowl that holds the soap. I rinse the brush with the hottest tap water, shake it out again, pick up the lather and some more out of the bowl, and rework the lather on my face, again adding drops of water to the brush till I'm satisfied with the consistency, containing as much water as possible.
Shaving in the bathroom, I never had to re-apply lather, for reasons of it drying out.
Shaving my wifes legs, however, outdoors on a sunny breezy day, is another thing. Lather made from a puck of soap dries out while applying it, in such case. Using lathered-up shaving cream makes a big difference in that case.
Hopes this is of some use to you,
best regards,
Bart.
