Yeah, I suppose if someone told me they'd been with 80 people vs 12 it would be significant difference (more than if someone had been with 2 vs 4 or something close together). I have no real problem with people who've been with a zillion people though. I think everyone has a different view on sex. Some people see it as something sacred, some as something fun, some as something serious, some as something trivial. I think it's upsetting to think of young teens having sex though. I see girls pregnant and realize that I wasn't even kissing at that age.
I suppose it becomes a non issue to those of us who've been with the same person for years.
