I can only tell you how I learned to embrace my own - through studying them. I look at them often and think about how they were created. Through growth and change, puberty, reality. How they are completely natural, unique and personal.
But I know how difficult it is. My newfound pride in my lightning bolts has come on quite suddenly - I think mostly as a result of becoming more familiar with stretch marks on other bodies, normalizing them. So many people are insecure about perceived “imperfections” like stretch marks and uneven boobs when they are honestly SO NORMAL, it breaks my heart.
Check the stretch marks tags for some stripey belly inspiration. I hope you can learn to own them. <3
I should also mention - if you’re mostly worried about what your boy thinks, if he loves you, then he should love EVERY PART of you.
