Hi there,
Hope you are feeling better and less separated from God as you appeared to be suffering from at the beginning of this thread.
Its pretty simple, there is probably not one thing exists that has not been masturbated over by someone. Masturbating over a dragon in Gods eyes is no worse or better than thinking (i said thinking cos thre is no wrong in masturbation, there is only wrong in some chosen thoughts some may have) about the man/woman that you are not in a relationship with. Anything outwith that and we are on the Devils bus, no wonder people are so seduced to the thinking sex is bad therefore - when its not.
Its a subject many choose to delude themselves on so they can appear less sinful than others to their own minds. So one one hand you are deluding yourself here by thinking the dragon things is something extreme or more sinful than other things and anyone reading that thought it was adverse are deluding themselves too.
All sins are equal.
The devil is very good at manifesting himself in sex to cause, doubt, fear, separation.
And there is where your real issue is, not what you did at all, but the fact you so feared you had done something unforgivable you doubted Gods love for you and threfore his forgiveness too.
You take it to him, he love and forgives - without condition.
No middle man required either!
Who are you not to forgive yourself if God will have?
