Thanks Deige, I do have one final question. I don't really have any tight underwear, so I was thinking about getting some duct tape and taping the QF to my very inner thigh, right beside the testicles. That is, the side that's going to be taped is not the side that has the heat pack rubber banded on. I'm going to wear baggy pants so I'm sure no one will be able to see. What do you think about this idea? Any other suggestions for concealment?
