Blow job

I was giving my hubby head. I told him I wanted to try to swallow his cum. I've never actually tried. The smell is off putting. When he finished in my mouth it was almost an instant reaction, I started puking. I ran to the toilet. He felt bad, but I told him I wanted to try. Before we tried, I told him it was a possibility.

Is there a way to swallow with it going straight down the hatch, less risk of throwing up?
