You can beat the pulp out of my head, but nuh huh! nothing and nobody is going to convince me on that!

Exactly.
Glamorous, think about it for a minute:
how does the guy know she has stretch marks in those areas anyway?
Is she dressing in a way that shows them off (low rider pants + extra short shirts, short shorts, etc)? --If a man doesnt want to marry a woman after seeing her stretch marks in this scenario it may not just mean that he is turned off by her, it may also mean he doesnt prefer to marry a woman who dresses that way..that's all.
Are they in an intimate scenario that he sees them? --If a man doesnt want to marry a woman after seeing her stretch marks in this scenario....tell me i don't need to go on please???
Are you simply talking to him about it? --Alot of men dont' like to hear women obsess about this stuff. At least i dont think they do.
VERY WELL SAID!
