Maybe you need to incorporate more water in your lather. That will give the lather more slickness and will not dry as fast on your face either. Now I don't shave with straights but it sounds like you need more water. Which soap are you using?i have a similar experience as op. i use straight razors which i know are shave ready but even with prepping my face and using something like a preshave the razor doesnt glide. it cuts amazingly but no glide i attribute this to the shave soap as ive noticed its similkar but more intense wth soaps that are know not to be the most slick soaps also despite hoiw much water i ad or how long i lather the soap it starts to dry ot withing 10 seconds or so of applying meaning by the time i have applied and wash and dry my hands it already looks not wet or moist even. so i have to apply more. its a conundrum for me as i do add water to make it look slick in the bowl but it starts drying very quickly if im trying to be thorough on my face one side will be pretty much dried up before i get to the other side. may have something to do with my skin being dry so i may apply some nivea cream a few minutes before shaving and see if that helps
