How to deal my nightmares of previous affairs.?

Answer 1

I don't understand whether you are dreaming about previous sexual encounters, recalling them with agitation or whether there is a more direct trouble like a past boy or girl friend who is making trouble. I assume you mean "deal" with "my".

In any case what you should do, if memories are troubling you, is to learn from past mistakes and not repeat them. Also if they are real "nightmares" a little honest forgiveness of yourself and any partners may be in order and may help.
