TITLE: Do my boyfriend's [24M] past relationships mean something about me [22F]?
POST: This is a two-part question, so stick with me.

Question 1: I know this is shallow and so judgmental of me, but here it goes: With the exception of one ex, all of the girls my boyfriend has dated just look... trashy.  They're ALL the same "type".  I don't want to describe them in detail because I don't want to offend anyone.  I don't know these women personally so I'm sure they're all perfectly nice.  I, on the other hand, work in a professional environment so I have to dress, look, and act professionally.  My boyfriend has even said that I have the best manners out of anyone he's dated.  

Does he want women with no ambition or class?  Does this reflect poorly on me or is this a good thing?  Do I somehow fall into this category without even realizing it?

Question 2: My boyfriend was with his last ex for 8 months.  They lived together and both said "I love you".  We have now been together for 8 months.  He just said "I love you" for the first time two weeks ago (I said it several months ago).  His mom made it seem like *such* a big deal that he finally told me he loves me, but then I found out he said it sooner with his ex.  We don't live together, and I don't imagine we will for a long time.

Should I be worried that our relationship is progressing slower?
TL;DR: 
1) My boyfriend's exes are all trashy.  Does this reflect poorly on me?  2) Should I be worried that our relationship is progressing slower than his past relationships?
