I asked THE QUESTION to my gf recently. She was reluctant to tell me so she asked how many i slept with. I told her 13(which is true) so then she told me i was number 10. She said she never had a 1 night stand though, shes only been with boyfriends or guys she was seeing. Still, 10 seems pretty high for a 21 year old. And who knows, she could be lying, she could be with 15 or 16. But i get the feeling shes telling the truth.
