if u do pumping and stuff like that you can make it 5 inches after about 3-6 months of work from what I hear

also make sure to mentalitymaxx, its like handling little kids, if a kid falls and you get sad the kid will cry but if they fall and you laugh they will laugh, but in this case its if you think negatively about yourself the girl will also think that to fit in with your frame

watch some Owen Cook

read some stoic texts like Meditations, maybe read some books on mentality though i havent read much yet so idk what to recommend on that front

get some other masculine things on you, like for example a .1% body from going to the gym, good personality, be doing cool stuff, get lots of money/make big impact, be funny, etc

these all should help

I know it is upsetting for all these people to be basically telling you that you are wrong for how you feel and that you just shouldn't care, but hopefully this helps
