lesbian relationship insecurities

I have a long distance girlfriend. 
Yes we do send each other nudes (in our 20s) lol 
Anyways I'll just get straight to the point, I feel more insecure about my body (I have a child) so my body isn't perfect anymore. I'm still on the petite side but my SMALL boobs aren't as perky anymore.... my girlfriends are. 
I have stretch marks everywhere. 
She doesn't really have that many besides from working out. 
I'm just scared she will think I look gross. 
Mostly because I've been told that by guys my whole life that girls shouldn't have stretch marks. 
OH ALSO her nipples are small. Mine are like.. medium. It doesn't help that my boobs are small.
