@ayswarr765,
I'm gonna say "it depends"
If you're having sex with two guy in one week, per week, for many weeks it makes you kind of slutty (or a professional).
If you're having sex with two guys in one week and it's kind of not your style and you're questioning your behavior, you're fine.
If you're doing it because you were drunk or high or something it might indicate an altogether different kind of problem.
