Well call me unusual but even if my future gf , partner, or wife had a belly like that and they had never given birth I would still be interested in them. homestly Id be MORE interested in them if they had had never had children cause nah fugg dem kids , too expensive!
The way I see it is that to be covered in scars, blemishes, acne marks, stretch marks, cellulite, insect bites, self-harm scars, burns, etc.... is to be human. Human skin has always been and probably will always be imperfect. Deal With It. If you cant accept the blemishes that a person has om their skin which they had no control over having them there? You dont deserve to call that person a partner.
I have a bunch of blemishes on me cause I ALWAYS get acne (I have to keep a boringly strict diet or else my acne goes absurd. Ive eaten nothing but homemade bread and eggs for the last month . THATS how boring and strict my diet has to be....) so I see no fault in another human who, just like me , is covered in marks and imperfections here and there. It is what it is. To be human is to be covered in blemishes and imperfections.
