I nut fast.
With bytches I can last maybe 5 minutes and that's a good day.
With trannys I'm lucky to last 2 minutes.
Any pointers r advice

I'll bite the bait.
First off, man. What's making you nut fast? (Pause) Now I refuse to believe any male of sound mind can't tell what's going wrong whilst inside some trim unless he just simple as all fukk and just happy to gave his dikk in some wet, not caring about performing or lasting or nothing, ole male Grasshopper type fukkers, but I digress.
Is it sensitivity? Feeling just too good and you can't hold it in? Or do you just push for the goal the minute the drawers come off 'cause you only concerned about releasing that dopamine with a female induced nut?
I can only (and will only) talk about MY dikk and what I do with it

but I know if certain factors are in play (Location, unprotected blowjobs, Aggressive Cowgirl etc..) I ain't lasting the industry standard 30 minutes so I gotta mentally prepare to break that shyt up with some foreplay or offset the tempo if I feel like I'm about to nut by focusing on her for a bit....but you gotta know what gets you off and how fast (pause), breh.
Plus, you gotta know your refractory period and how to make it work for you. Your refractory period of that period of time directly AFTER you nut to when your body allows your dikk to grow hard again through natrual arousal. You ever had that thirsty moment when you about to smash, and you telling homegirl she gonna get it in every room

(Coli Edition = 10 different porn tabs open with intentions of nutting to each one), you throw one off and all of a sudden shyt like The Big Bang Theory or C-Span looks MAD interesting and you ain't wanna fukk anymore?

Refractory period, breh. Your thirst/arousal meter done been reset and your dikk goes back to behaving like it should for a bit. Most dudes who have a problem with stamina usually rub one out before they have it away so that it takes longer for your dikk to produce the whole orgasm package like it did before that first nut that started the refractory period, so you can always try that if you ain't already.
Anything else outside of that, you might have to work on internally/mentally. shyt like "Edging" works wonders for some. Best of luck to you out there, man.
