Hi there, thank you for posting your question. My answer is not intended as a substitute to visiting your own doctor but I hope I can be of some little help.
Can you say if your sexual dysfunction is one of not having any libido or desire in the first place? Or is the problem one of having desire alright but not being able to respond not being able to get aroused or wet.
If your problem is one of Sexual Arousal Defect or SAD syndrome then HRT may help but it has to be of a strength not to allow all the nasty breakthrough bleeding that you have been experiencing. This needs to be teased out more and will take a little time to do. It is not that difficult and you are very fixable. So don't give up.
Dr Andrew Rynne.
