Just temporary solutions. You should work on it yourself. Plenty of resources online.
Edging is a good one. As you start to cum stop and go do something else.
I have a young FwB who would blow a load when I only breathed on his bellend. 🍄
He was all embarrassed but we've had fun and worked on it together.
He can fuck me for 30mins now. Lots of position changes but he's lasting much longer.
