I am sure that many people wont agree with me, but here goes.....
I think that the number of the people does matter. My beliefs and the way I was brought up was that sex is something that is shared with someone that you love and care for. So, when people have slept with even 8 people, I find that outrageous because I cant believe that that person has been in love 8 times. Surely, they slept with 8 different people without love, and it makes me think of what kind of person they are.
I am not judging any of you based on numbers or anything like that, but I would think twice about someone I was considering sleeping with if I knew their numbers- not to mention any sexually transmitted diseases!
