I am 33 years old and I ended my LTR (10 years). This was my first girlfriend excluding some random makouts before. So I am not very experienced with many womans. I have a problem because of this because after making out with new girl I started to judge her with White Knight Attitude. So I started to asked myself is she a whore? How many boyfriends she had? How many ONS she had? I started thinkging about it during sex and this get my mind numb and made tool go soft.

I hate what happened and I am afraid it will happen again. I suspect it comes from the jelousy which in turns come from my small experience. I know this feeling is hurting me only. Are there some ways to stop such thoughts?
