<human>: Would like advice on how to deal with this and or make her feel better about it. I think about 1/10 to 1/4 times she tries to give me oral I can't finish and I believe it makes her feel insecure. I have tried telling her that many guys aren't ever able to finish through oral alone and it doesn't seem to help. I think it is due to underlying insecurities about herself [she sometimes calls herself a reacher(like I am above her) and she says she wonders how she ever got me] 
 

So I guess it is more of a two part question,
How can I help her from getting upset after a unfinished bj?
How can I help reduce some of her insecurities? (I have recently encouragered her into lifting to hopefully boost her confidence)

Could you distill the essence of the text into 1-3 sentences?
