I think any healthy couple or individual who can provide a loving home to a child is a great situation. Who the adoptive parent or parents sleep with should not be an issue if it is a loving committed relationship.
A child can have heterosexual parents but their homelife can be a living hell for any number of reasons--abuse, alcoholism, etc. Having heterosexual parents is no guarantee that a child will be in the best home they can be in.
Gay parents make a choice to bring a child into their home. Heterosexual parents might want to have kids, but it something that is expected of a couple. It isn't something expect of a gay couple, however.
I know many gay people who are single or in relationships who have kids and are doing a wonderful job of raising them. There is a lot of research to back up the fact that gay parents even make better parents. They have to fight for their right to adopt children. Some straight parents could care less.
I hope you are happy.
