Ageless used to have a section for same-sex couples but it got dropped, probably due to inactivity.
Even "straight" people are posting here less and less. I think part of the problem is that more interactive web venues like Facebook, YouTube and Skype are replacing traditional forums for social interaction.
You might try to Google it and see what you find. You may run across a more active forum that suits your needs and interests.
Like Abraham Lincoln once said, "You can't believe everything you read on the Internet."
