Had my first shave today,

not too bad in the sense I'm not cut to shreds, but could of gone better. The brush I ordered hasn't come yet so I nipped to town and bought this body make up brush as a replacement. Man was that thing useless so in the end i basically shaved with what felt like nothing on.

What should I do while I wait for my brush do you think, wait or just use gel?

Also, my blade felt like it was dragging in the hairs, is this because of the poor lather(or lack of it), poor technique or blade not shave ready?

Finally, I struggled a bit with my left hand and couldn't trust myself to do the intricate bits around neck so got old cartridge out to finish up, should I persevere slowly or try to use right?
