EMFs, Heating Pads, And Safety

I’m wanting to buy an electric warmer, but am a little concerned about electrical radiation having an impact on body, including sperm. I am interested in optimizing my own penis enlargement and know the importance of heat to maximize gains and minimize downtime, but I try to limit unnecessary EMFs. I am considering buying the electric warmer from the Total Man Shop but I know there is EMF being emitted. Has anyone ever considered this conundrum? Is there a low level or no level EMF strategy that is both convenient as an electric warmer sans risk? I’m considering buying EMF fabric (enough for 2-3 layers) to wrap around the heater to reduce the majority of leaked radiation, but would like other ideas or feedback.
