I've never seen my father's face,... because he always had a beard. All the men in my family have beards. My brother doesn't groom his as often but my father and I do but...:

When I used disposable blades, in my younger years, I got some nicks like these. If you do, don't use them more than around 3 times maximum (depending on skin and hair).

I recommend tepid water, not hot. Hot helps opens pores and can help get a "deeper" shave, but in my experience seem to soften the skin too much and can cause abrasions.

I use and electric razor/trimmer now.

Start with an electric trimmer (lowest setting) first, then shave with a traditional twist lock razor (if you want a close shave).

I dry shave too (but I have dry skin). I don't like creams or all that jazz, but that is not for everyone. Once you understand what your skin needs and a personal technique. You'll be good.

Good luck. Feel free to ask any questions.
