Masturbating as an Adult

hello hello, i’m a 24F who grew up in a somewhat conservative asian country. i moved to a western country in my early teens. my knowledge on sex education is a mix of both cultures.

i recently bought a vibrator just to explore. every time i use it or at least try to use it, i’m not sure how to explain this feeling but it’s kind of like guilt in a way? cause back home this kind of behaviour is and will not be tolerated, but here i know it’s normal with some even encouraging it. i know i’m an adult (and a virgin at that), but i’m somewhat lost. i can’t help but to compare myself to people i went to school with in long-term relationships and some already having kids.

am i the only one who feels this way? what can i do to relieve my anxiety?
