Hello Angel: Well... since I'm an old male... sort-of... (it's complicated) I'm probably not the best person to be replying to your post. But the one thing I do know is that the more you focus on how things are going in bed, & worry about your lack of performance, the more difficulty you're likely to have. I obviously don't know what started this difficulty for you. It could be any number of things. But the concern over it simply makes matters worse. This may be something to talk with a therapist about.
Beyond that, I would just like to suggest that you consider putting this Thread on the Women Focused Forum. You may get more & possibly better replies there than you have gotten, or will receive, here. Best wishes...
