Ye its kinda brutal, specially if ur kinda late to bloom when it comes to sex, it makes u depressed cuz u think somethings wrong with you, and then u maybe glow up at some point, get a girlfriend, u get down and dirty, and now u cant cum or keep it up.

which often makes her think bad thoughts which further spirals u down.

Shit sux so much... Childhood Trauma is honestly worse then torture (sorry bit of a rant, but i related to ur story abit)

but as others have said, if u like her, make her understand if shes ready to understand, otherwise just try to forget her, plenty of fish as they say.
