Being pee shy is by no means uncommon, as others here will no doubt tell you, and there are plenty of guys who suffer in silence, guys for whom using a public toilet is a major sourcec of unwanted anxiety. However it's a problem which stems from the workings of the vmind rather than any pysical cause. The brain is the most powerful organ in the body and we sometimes underestimate its power. I didn't quite understand the connection you seemed to be making though between being pee shy and your sexuality. I'd have thought the two were entirely separate, unrelated issues.
