I am straight insofar as I have never had sexual contact with a man. But I find it very interesting and arousing to look at other men's cocks. This is true in porn and on sites like this one, and also in real life situations where I see men nude (locker rooms and nude beaches), though there it is mainly just "interesting" not arousing. I feel that this is natural thing. I'd guess that everyone who is on this site shares my interest. Do you think all men are interested, maybe even very interested, in other's penises?
