I have often stated that if people know a gay person for a long time before learning that he is gay, a negative response is far less likely. For that reason, in general I see it as a mistake to tell people immediately upon meeting them that one is gay. When possible, is better to let others figure that out over a period of time. In any case, it is not good idea to put others under pressure to make a response before they get to know you unless the situation is such that there is no choice.
It is most effective to present being gay as if it is a mundane everyday thing that one would hardly even think about. If it is presented as an issue, it may be perceived as a challenge and there is more likely to be a negative response.
In my opinion, the couple in the following thread are simply creating problems for themselves that they could avoid:http://www.realjock.com/gayforums/4031488
