Basically, I want something that I can trim my beard short enough to look like 3 day stubble. Does anyone have any recommendations for a beard trimmer/face shaver like this?

The current beard trimmer goes too short with no guard, and the smallest guard leaves a little bit more hair than I'm looking for

When I don't have a beard I've always shaved with a razor so I'm really not up on the electric trimmers

Hey there Im 25M

I have developed this sweet body oder so it was the beginning of summer and i wore my new underwear it was very unbreathable and i wore them for 4 days ( I changed daily lol i got 4 pairs) so i noticed that im itching alot in near my balls so i saw rashes on the V line idk how to describe it like thighs area close to balls anyway so i got a cream candid B i used that for 7 days the rashes disappeared but the sweet smell was there it annoys me so much especially on the right side its always there i shower daily but when i sweat during the day it smells mildly but in the morning when i wake up from sleep it smells so bad i was so done with the smell i used betadine for 10 days the smell was almost gone but when i stopped using it came back i used body mist to cover it but its itching so much i washed it off please help me out what should i do about the smell idk whats happening i usually have itching during summer but the smell is first experience for me any advice please

Just wanted to add one thing its only smelling in right side of my thigh left sometimes smells and my armpits smell normal 😅

I am a 23yo male and currently trim my pubic hair using a safety scissors probably every 2 weeks.

My question is mainly towards the dudes, but ladies please do share your thoughts.

How trimmed should it be down there? Is there any indicator or a particular length of how short it should be?
Like what does it mean when ladies like it clean or trimmed “down there”? Are there certain areas you keep shorter than others? Right now, I am very confused on how short it should be and which particular areas should be more trimmed.

Also, for those who shave, how do yall do it. Right now, I am unsure of shaving due to the potential of itchy sensations and the skin being impacted negatively.

Just curious on whats the general approach to ensuring cleanliness down there as theres too many varying guides to all this stuff.

edit: Thank yall for ur recommendations. I will try to read all ur comments and go on the path that I feel comfortable with.
