How do you know if you are a homosexual?

There is this two stalkers on the net that i know of .One of them is from Turkey, He is a Washer/Dryer repair guy working for Bosch in Bursa. He is in his late 30s and never been married. The other guy is from Ohio and being dumped by his wife because she was cheating on him with his friend and literally hates women. He hates his wife too. On his face book account he claims her as his wife just to get back to her. He once told me that the family get to gethers are the only way he can torture to his ex. These two systematically stalking females and sometimes males together. One of them is really good on computers. He is hacking the emails and face book accounts and helping his partner and giving the information to the American guy. I saw the US guys photo and once saw the Turkish guy on the webcam. They are so similar in build and physics and features. The US guy is quite feminine the way that he talks, thinks, looks..etc. The Turkish guy is keep telling he is not a womanizer and females are no interest of his. He claims, he is only looking for friendship. Yet he is stalking the females the other guy was interested in and giving him the info and helping him to play with them. It Looks like the US guy is so involve with pornography and relate everything with sex. It is almost like he wants to prove himself that he is not a homosexual. He is also quite fragile looking man too. Everything he does sounds like to prove others that he is into females and he gets sadistic when his preys don't act the way he wants. The Turkish guy is watching him cyber with other girls.Both of them claim to be Muslim so they can motivate other low lives like them to participate their online activities. The Turkish guy is a dumb man. His intelligence is really limited. Is it possible that he is not gay.Do you think there is something homosexual going between these two? Is it possible that a person can watch porn, stalk females on the net just to prove that he is not gay?
