What is more comfortable going to a male/female urologist to check for testicular disease/cancer?

I have been having sudden pain in my left testicle for a week now, and I feel like it is a bit bigger than my right testicle. I am really dreading the thought of going to a doctor, I hate the idea of a man touching my genitals yet I feel like a perv preferring to let a female doctor do it. What do you recommend / feel more comfortable with?
