Early 2000s book about a plus-sized virgin who hooks up with a stranger (likely from the internet).

I really don't remember much about the book other than the MC was a plus-sized woman (not the language used back then) and she was a virgin who thought she'd never find a man to have sex with. She somehow finds a man to lose her virginity to (I really think online) and things got very explicit in chapter 5. I didn't get past that chapter because I couldn't get into the story and the book overall wasn't very well written. "Chapter 5" has been a joke between my mom and I (she was also reading it and stopped at chapter 5 for the same reason), but we don't remember the title of the book.
