Suzy,
Believe me, I questioned it a whole bunch too. But, I am taking him for his word now. I have had one night stands that I am not proud of. They were hetero one night stands, but they were awful none the less. We will see in time. That's all I can say. I can't hold his past against him. I can only deal with what he does from here on out.
Edited to add:
I have read posts where straight CD's were talking about the fantasy of it. So, I just wanted them to know that once you make a fantasy a reality, it becomes just that... a reality.
