Hello and welcome Mand.
The 38c is a big heavy razor and as already suggested, dont apply pressure with this one, just let the weight of razor do the work.
I find personnas and 7o'clock yellows are good with the 38C but each to his own.
You might want to try Body Shop Macca root cream, its inexpensive but a great performer.
Also, palmolive cream for me is better than the stick.
happy shaving.
regards, beejay
