Chafing

Chamois Butt'r or some variation. I never ride without it. Personally, I find the Euro version works better with my skin, but it does contain menthol and witch hazel, so consider yourself warned if you try that version.

On race day, I like Skin Sake, because it does not come off in the water or with sweat. I put it on before the race starts, and I am good all day. I have never done anything longer than a HIM, though.

HA!!! I am really lmao cause I have Boudreaux's on right now! As we all know water or sweat ain't no lubricant!
I start with a good pair of Pearl Izumi's or DeSotot Tri shorts, Butt Butt'r for the mid to back area and A&D ointment in the creases and folds where my legs come together. Also for the male anatomy.
I use a combo of Boudreaux's and A&D for after/overnight as well. I am loved by all family members on beach trips cause I have the chafing first aid down pat. I try and stay away from soccer style shorts when running and look for some that do not have prominent liner stitching. Cold weather exercise can really fool you because you dont think you are chafing until BAM you hit the shower and then you know the places that you missed.
I have stopped using chub rub but will occasionally on the arches or tops of my toes/feet if I am trying to get my feet used to running with no socks for a quick transition.

Hope this helps. I have scars cause I foolishly thought they were cool and chicks would dig them.

I assume that cause you are wearing a tri-short, it already has a thin chamois.

Really, the main things that helped me were a proper fitting seat, making sure the lycra is tight ( loose will rub ) and there are plenty of chamois creams available at your local bike shop, though lately I've been using a stick of body glide or some vaseline.

Over time your nether regions will get more leathery, I pretty well never use it for cycling anymore, only for running, and only for specific shorts, or everywhere if it's particularly long.

Chamois butter and/or A&D ointment depending on the specifics. IMHO

in addition to ample lube...the seat / shorts can be making the problem worse.

for example my Adamo saddle was too wide and pulling the "fork" in with zip ties helped to eliminate chafing.

different shorts might help too.

Good to analyze the areas that are contact with the point that's chafing
