Just a normal girl from Germany. I am starting to work out a little more again, because I gained some, but I am still happy about my body. [F,32, 160cm, 77kg]
It took me until my 50s to stop being self-conscious about my slender body and skinny arms. Exercising more helped a bit but it was mostly in my head. My advice - love yourself now! (The sign was for a Twitter pro-nudity campaign)
