Vacuum pump before injecting Trimix

[wgs743]

I have injecting Trimix for about a year. Occasionally I miss the CC because my penis is still small. Hand stimulation helps, but am curious about using vacuum pump to get it big and fat for injection. Amazon sells a bunch with prices from $15 for bulb pump to $165 for electric deluxe model. I am thinking of trying a cheap one to experiment.
Does anyone have experience in using pump to aid injection? Any suggestions on technique?
I am concerned about possible bacteria from the pump getting into injection site even though I always use alcohol wipes.

I tried that......once! It was pretty painful if I recall. But your experience might be different.

WGS..
What formula of Trimix do you now use?
As far as pump prior...I wouldn't bother. Just use vigorous stimulation..enough to make a little *chubby*.
Make sure to stretch a little to expose area properly.
