I use a 10 dollar b eard trimmer from target and "pre-shave" with that on the lowest setting and then actually shave with a gilette mach 5 fusion turbo xx holyshitcutyourhair. It works and I get a damn good shave, but literally the next day I'm already growing stubble. My skin is really sensitive too so I can't shave everyday, or even twice a day. I normally shave Sunday night, Then again on Thursday morning but I hate having to wake up early for work. I would like to get laser hair removal but I don't know if one day I'll end up wanting to grow a beard or something =/
To anyone who has problems with shaving with a straight razor, try this:

It's quite good.
