Hey everyone, I just got my first straight razor. I thought they looked really cool and decided to try it, i dont have a tonne of facial hair but still enough to have to shave every 4 days or so. My fist shave went fairly well, i lathered well and went WTG everywhere.

The only issue is my face is a little sore and a bit red the next day, razor burn i guess (never had this before regular shaving) what do you guys think is the cause? I did 2 passes total, i had a hot shower before i shaved also, is aftershave a must when using straight razor? Thanks in advance for any help, hope to shave like this for the rest of my life!
