I have a little of both. Never had a baby, but I got some stretch marks from developing during puberty - very faint on my breasts and little more noticeable on my thighs. Cellulite... well that's par for the course too. While I don't love those 2 things, at the same time they are part of my body... and this body has gotten me through a hell of a lot of hard times AND brings me a hell of a lot of pleasure! I can accept a few imperfections on account of all it's had to deal with and all it's done for me over the years.
Kinda like my car, a tree fell on it in a bad storm, and so it has some dents & scratches. Since it's old, insurance totaled it... but it's a great little car! It's reliable and has been with me for so long, I keep on driving it - and I'll tell you, when I look at it through the eyes of love, I don't even see the dents or scratches.
