Is it ok if my current gf had sex with 4 guys including me?

[sparky]

She had sex with her bf that she dated for 2yrs then they broke up when college started in october, since then she had sex with 2 other guys and me in march...so shes at 4 now...we're both 18yrs old and i was just wondering if its bad that shes already had sex with 4 guys. Both the guys were only once, and then i was the most recent. One of the guys stopped talking to her. And then her and the other guy never planned on dating,just knew eachother a long time
