Sexuality is one of the most complicated fields of psychology for a very good reason.
To use a cultural example, in Japan nudity in bathhouses is accepted, but there are still those, independent of their cultural reinforcement that "same gender nudity in the bath is fine" are uncomfortable around any sort of naked people. And the reasons for this are as numerous as branches on a tree.
"If you actually were a straight guy and saw a man in a speedo, there'd be no reaction." is presumptuous. There's even an argument that there are different gradients of "straight."
By your logic, since I look at a man and HAVE a reaction, even if that reaction is "uncomfortable queasiness," I am automatically not straight because, under your definition, straight men "should [have] no reaction" to naked men.
Conversely, by applying your logic differently, if a gay man looks at a naked woman and has any sort of reaction, he is automatically "not gay."
Your logic is unscientific and flawed. Sexuality is not something with any sort of absolutes to it.
