Feeling a bit overwhelmed and confused

[TwisttheLeaf]

I used to speak to a sexual health therapist for about a year about it, but decided to end it because I thought I had conquered it, but think im not ready yet.

This right here sounds like you would benefit from going back into therapy for this issue. Clearly it -was- working, as you thought you were cured. Sometimes, regressions happen. Sometimes more help is needed. I'd say it may be a good idea to go back into therapy to deal with this a bit more.

That said... Perhaps you need to look at past partners as what they are.

That is, not as threats but as FAILURES. They, for whatever reason, are failures. They are not as good as you, because you have what they couldn't manage to hold onto.
