Scott,
my comments disappeared. I'll try again and make it shorter.
Releationships end for a variety of reasons, gay or straight. The joy of sex is important to many releationships, but not all. You had found a partner that sex was not important to, you can find another.
You are taking hormones that have side effects, depression is one of the side effects. Please try to remember that when self pity comes into your thinking. It's ok to visit the house of self pity, just don't move in.
Please find a professional therapist to talk to. Find out 'why' sex is so important to you because sex is not an essential part of life like food, water and shelter is.
Not trying to sound flippant but Attitude is Everything. A therapist can help with that.
Just because your dingy does not want to sail does not change the kind of person you are. You help others and and can continue to help others and make a difference in the world, in th words of Jim Valvano, don't give up, don't ever give up.

My therapist asked me that question directly and I told her it was the intimacy and also a feeling of power to dominate someone in a very primal way, but always in a way that the other person wanted (i.e. I NEVER pressured anyone into anything non-consensual).
She tied it back to me always wanting to be in control. Then she asked how many hours a week I spent on sex previously and I said "probably 2-3" and her response was "OK, so the other 137 or so hours haven't really changed that much" and I sort of laughed at the absurdity of it.
She's very good in that she told me her goal upfront is to take something traumatic and help me figure out how to turn it into a way to grow and change but she also said the process isn't going to be easy and that there is a definite loss that has to be properly grieved with sadness and maybe some anger.
