There isn't much I can add to what already has been said. I also tend to take things at face value until or unless there is more information to change my outlook. If a guy says he is straight, I have to assume that means he is not romantically interested in men--that doesn't mean he won't ever have sex with a guy---that is about circumstance and chemistry, although most truly straight men do not have any sexual desire to be with a guy. There are some gay men that constantly pursue straight men, and I suspect that it has more to do with cultural perception on what masculinity is than anything, else, and a mainly homosexual man wants a MAN, not a woman, and that includes the physical and cultural perceptions of what makes a man. I have straight friends I have been attracted to, and gay friends I am not attracted to--that is attraction. How we treat each other as friends under these circumstances has to do with respect. If a friend is hitting on you, and you have been decent in rbuking his advances, and he is still hitting on you, he isn't respecting you, period, and is being a lousy friend. You then have the choice as to whether to keep him as a friend. You may choose to give him a clear choice--stop the advances, or the friendship ends. You may choose just to drop him. If his friendship means enough to you to put up with his crap, then you have to accept it--it is totally up to you---but he likely won't change unless he values YOUR friendship enough to keep his hormones in check when he is around you. He may not be capable of it, and if not, then the friendship is probably as painful to him as it is to you, and you need to end the friendship, tragic as the reasons may be, for him to move on. The guy I loved the deepest in my life was straight, and it mentally screwed me up for a long time. I accepted his sexality, and who he is, because I loved him for who he is. It took many years, and him moving far away, before i was able to get over him, and we haven;t talked in many years, but he will always be the person I loved the most--but it was not meant to be, and I accepted that. Again, nothing really new to add, just maybe one more perspective. Good luck!
