Is it dangerous to masturbate with a high pressure suction hose?

Pressure and suction are two different things. I would find a boyfriend or girlfriend to take care of this issue because it may be safer that way. I would only recommend using a Dyson Vacuum if its suction that you are seeking and if its pressure I would use a craftsman 30 gallon single stage compressor. I would discontinue use of any of the two if any sudden pain occurs during the deed.
