I'm 36 and a swinger. I don't got long left to breed but I'm a hell lot more likely to fall pregnant to a random man than my husband with how risky I get π
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)
