Is it normal be a hetro-sexual and having no relationship experience?

There is no basis for this statement either. Seems to be bias speculation and more than a little bit condescending.

Is it really a stretch?  How do the ladies fair in Hollywood?  They certainly become much better actors as they get older.  But they're for the most part shuffled off, and the only hope is to get enough plastic surgery to pass themselves off as younger.

I didn't think this was a contested idea.  

And older women are competing with younger women when it comes to desirable older men.  So who's that leaving in the prospect pool?

It is still condescending, and still speculation, yes.

Lets breakdown your argument.

You are using women actors in Hollywood as a representative sample for half of the human race.  That's a great idea. [/sarcasm]
Women in Hollywood have a 'shelf date'.
'Shelf dates' are bad for polyamory.
Therefore all women are going to have a problem with polyamory?

This is not a valid or sound argument.  I don't know how to make it any more plain.
