Am I having sex with too many people?

I'm 18 and I've had sex with several different guys and by several I mean double digits. I like sex just as much as the next person, but I feel like I'm over doing it? I only ask because I care way too much about what people think and feel like everyone thinks I'm a "dirty whore" or something lol. I mean I prefer one night stands rather than commitment. Regardless I'm still going to continue to pop my pussy but I thought it'd be nice to hear your opinions.
